Eagle Vision

"I've seen its like before. Glowing like moonlight on the ocean. Ah! Right. I know this feeling. I have since I was a lad. It's like using every sense at once, isn't it? To see sounds and hear shapes. Quite a combination."

- Edward Kenway, about Eagle Vision.

Eagle Vision is a dormant sixth sense that humans possess, as a result of being created by the First Civilization and also through interbreeding between some early humans and their precursors. Though each average human holds the potential to utilize it through an intense and very long training, some gifted individuals display a greater concentration of the necessary precursor genes, and thus are more likely to naturally exhibit Eagle Vision as well as some of its more advanced variations.

Those who possess the gift are able to instinctively sense how people and objects relate to them, which manifests as a colored glow, much like an aura. Red indicates enemies or spilled blood, blue indicates allies, white indicates sources of information or hiding spots, and gold indicates targets or objects of interest. However, as Desmond Miles was – at least initially – unaware of Lucy Stillman's true affiliation with the Templar Order, it suggests the sixth sense is not entirely infallible.

When an individual masters Eagle Vision, the ability can evolve to the more advanced Eagle Sense. This stage heightens all the senses of its user, allowing them to detect the heartbeat of a target in the area, or even foresee a target's path. Some individuals also developed exotic variations of the gift; one application allowing its wielder to peer into the memories of their target upon killing them while another one allowed a gifted individual to become a kind of lie detector, knowing when someone was lying or telling the truth to them.

Third Crusade
The Assassin Altaïr Ibn-La'Ahad possessed Eagle Vision from an early age. His fellow Assassins knew of his special ability as well, and were the ones to dub it as "Eagle Vision".

With it, Altaïr found himself able to read the emotions and intentions of all those around him, driving him to perfect the ability in secret. In his later life, he would make use of it during his many assassinations and investigations.

Eagle Vision aided Altaïr in locating targets, and was particularly useful during his duel with Al Mualim, who used an Apple of Eden to create phantoms of himself. With his ability, Altaïr was able to pinpoint the true one from the crowd.

Ezio Auditore da Firenze
"Listen closely: Return to the house. In my office is a hidden door. Use your talent to find it."

- Giovanni Auditore instructing Ezio to use his Eagle Vision, 1476.

Ezio Auditore da Firenze, much like Altaïr, possessed Eagle Vision and made use of it to locate hidden passages, as well as to predict the intentions of his allies and enemies. Additionally, he was also able to see the map hidden beneath the pages of Altaïr's Codex with it.

Though it was never explicitly labeled "Eagle Vision", Giovanni Auditore da Firenze once referred to Ezio's ability as his "talent", and Salaì spoke of it as his "gift".

The Ottoman Assassins also knew of Ezio's ability, even before they had met him. When Piri Reis instructed him to use it to see through a smoke screen, Ezio pretended not to know what he was referring to, but Piri merely answered that "word gets around". Upon hearing this, Ezio asked that he keep the information to himself.

Yusuf Tazim spoke of Ezio's skill as his "legendary senses", and Piri once mentioned that Ezio was a "special sort of man, with strange gifts". Ezio himself also admitted that his senses were "more finely tuned than most".

Others
"The note told me to use my other eyes. Sometimes I see things that are not there. Drawings or waves."

- Giovanni Borgia describing his Eagle Vision.

La Volpe was thought to possess an advanced form of Eagle Vision, as it was claimed that he could "look through walls".

Giovanni Borgia also had Eagle Vision, which he used to locate and tail Francesco Vecellio through a crowd. He was also able to see images or drawings that were not really there, such as waves, arrows, and footprints; Francesco referred to Giovanni's ability as "using his other eyes".

Golden Age of Piracy
The Assassin Mary Read described Eagle Vision as the residue of life essence, attaching itself to every living thing around those with what she called "the Sense". She claimed that every person could harness the Sense, but most either did not know they could or were unable to truly use the power until later in life. Edward Kenway claimed to have known the ability since childhood.

Much like Altaïr and Ezio, Edward could identify enemies, allies, and targets, but he could also 'tag' these people, allowing him to see their location when out of Eagle Vision, even through walls and other obstacles. He was also able to see hiding spots, such as hay bales and bushes, which would shine with golden and green glows respectively.

Adéwalé, Edward Kenway's second-in-command and Jackdaw quartermaster-turned-Assassin, also possessed Eagle Vision, in similar capacity to Edward.

Colonial America
Shay Cormac possessed a form of Eagle Vision similar to Edward Kenway's, having the ability to mark potential targets. Besides hunting, investigations, and assassination attempts, he would ultimately use it to track down his former Assassin associates, following his defection to the Templar Order.

Haytham Kenway possessed Eagle Vision, though he was unable to mark specific targets. Haytham's son, Ratonhnhaké:ton also possessed Eagle Vision which functioned in a similar manner. During his early years, Ratonhnhaké:ton learned how to use his gift to improve his tracking skills, and would use his gift to hunt animals. He continued to rely on the Eagle Vision upon joining the Assassin Order, during his hunt for the Colonial Templars.

One notable instance of this presented itself while Connor hunted down one of the pieces of Captain William Kidd's map, contained at Edinburgh Castle in Jamaica, where he used his Eagle Vision to examine clues in order to reconstruct the murder of one of Lewis Hutchinson's victims, later finding the man's body and retrieving the map piece.

Aveline de Grandpré was one of the few known female Assassins to possess Eagle Vision, which functioned similarly to Connor's, though certain things possessed purple highlights such as blood and wanted posters. Much like Connor, she could use Eagle Vision to examine clues to reconstruct past events and crimes, aiding her in investigations and finding targets.

By the year 1784, Aveline had gained the ability to mark targets with Eagle Vision, similar to Adéwalé and Edward Kenway. It is unknown whether Connor or Haytham also developed this ability.

French Revolution
The French Assassin Arno Dorian possessed three variations of Eagle Vision during the French Revolution. The first was Eagle Pulse, a momentary vision that soon faded away. The second was akin to Ezio Auditore's Eagle Sense, a longer lasting effect. The third version was Communal Sense, allowing Arno's fellow Assassins to see what he saw, within a limited range.

Arno also showed the ability to view the memories of his targets, rather than conversing with them directly. He also had the ability to read the paths that guards would take, much like Eagle Sense, but only could fully utilize this skill once he read the paths on a map. Lastly, this skill appears to have been connected with his auditory system, allowing him to hear conversations far away with perfect clarity once he achieved a high enough vantage point and focused in on the locations. He appeared to be able to maintain great focus while using it, as even while climbing, shooting, or even killing, the pulse would sustain. Even when heavily consuming alcohol, he could still use Eagle Pulse, albeit causing him pain when used.

Industrial Revolution
The twins Jacob and Evie Frye possessed Eagle Vision, and while the exact date of the ability being uncovered is unspecified, both have been able to use it since around 20 years old. Their form of vision caused very little distortion in sight, causing the Assassins to see in muted tones of black and white. During this sense, they could see and "mark" targets from very long distances, and even identify individuals by names, objectives, and opportunities to aid them in assassinations. Targets would be in yellow, allies in green, enemy Templars and Blighters in red, and law enforcers in blue. The only drawback was that the twins would not be able to move around much, and were confined to walking.

The twins also utilized Eagle Vision during criminal investigations, such as a series of murders tasked to them by Henry Raymond in 1868, and the Whitechapel murders committed by Jack the Ripper in 1888. Through this sense, the twins could identify clues as well as mark their own observations and trajectories based off information acquired.

Jack the Ripper also possessed Eagle Vision of his own. However, his vision became unstable upon activation, and words related to his objectives would appear.

Modern times
"Try using that special sight you learned from Altaïr."

- Lucy Stillman to Desmond Miles in the Sanctuary, 2012.

By using the Animus to follow the memories of his ancestors, Desmond Miles also gained the ability to use Eagle Vision, likely as a result of the Bleeding Effect. Through it, he was able to see Lucy Stillman and Warren Vidic, shimmering with a blue and red auras, respectively. He was also able to use this ability to see the cryptic messages that Subject 16, Clay Kaczmarek, had written in the Abstergo laboratory with his own blood.

Clay also hid a series of Glyphs within the rendered Animus environment, which needed to be scanned with Eagle Vision to be unlocked. Similarly, the Rifts that the Glyph puzzles led to also needed Eagle Vision to be both seen and accessed.

During his escape from Abstergo Industries, Desmond found another application for his newly acquired power. Much like thermal vision, he used it to discover the code of a keypad, by seeing the heat signature of the fingerprints left upon the correct numbers.

Later, upon reaching Monteriggioni, Desmond was also able to use Eagle Vision to see a message that Ezio had left upon the wall of the Sanctuary stairwell, which bore the password to the Colosseum Vault.

While traveling through the Colosseum to the Santa Maria in Aracoeli, Desmond used Eagle Vision to locate a series of switches to open hidden entrances. He also made use of it to see the proper sequence of levers he needed to activate, in order to access the Apple of Eden hidden within the Colosseum Vault.

The Abstergo recruits who participated in the Animi Training Program were also granted an ability named Templar Vision. This rendered ability mimicked Eagle Vision, and was able to be used for approximately 3.5 seconds.

When he traveled to Osaka on 4 December 2013, Gavin Banks used his Eagle Vision to determine that the yakuza, not Abstergo, had killed the Assassin cell in the city, though this invariably taxed his energy.

Eagle Sense
"As Ezio matured, so did many of his stranger abilities, not least of which was a rare form of extrasensory perception – you know, what we Assassins call 'Eagle Sense' in its most robust form."

- Clay Kaczmarek's digital construct, 2012.

Mastering Eagle Vision led to the user being granted Eagle Sense. A more heightened form of Eagle Vision, it allowed one to focus on a target and sense approximately where they had gone, or inversely, where they would go. This was particularly helpful in tailing a target, or detecting the path a guard would take, in order to set up a bomb or lay an ambush.

With Eagle Sense, Ezio was also able to pick up cold trails, or locate disguised enemies. However, for the latter, he was required to concentrate harder and scrutinize people individually, rather than as a crowd.

Ezio also once used his Eagle Sense to follow the scent vapors of datura, and to diagnose an injured mercenary by listening to his heartbeat. As such, the latter technique allowed him to conclude that the man was alive but weak, and likely affected by some form of poison.

Scrying
Throughout history there have been two individuals who have shown an advanced form of Eagle Vision, whereby they are able to telepathically see and hear through the senses of animals, particularly Eagles. Two known individuals who have this ability are Bayek, an ancient Egyptian Assassin and Medjay, as well as nhiòte who was the daughter of the Colonial Assassin Ratonhnhaké:ton, and the granddaughter of the Grandmaster of the Colonial Templars, Haytham Kenway and Granddaughter of the British Master Assassin Edward Kenway.

Trivia

 * Assassin's Creed
 * An Assassin guard could be seen glowing red in Eagle Vision at the Kingdom entrance to Masyaf, but he reacted in normal guard behavior. This guard was Jamal, an Assassin who aided Masun in betraying the Brotherhood, and was originally intended to have been a target. However, the sequence where Altaïr assassinated him was cut, leaving him as a minor Easter egg.
 * In the original Assassin's Creed, movement was restricted while using Eagle Vision, and Altaïr was required to be at maximum synchronization. These requirements were removed in most of the succeeding games.
 * In Assassin's Creed, Eagle Vision was said to actually be the Animus' visualization of the Assassin's observational skills.


 * Assassin's Creed II
 * The users of Eagle Vision saw themselves marked with blue.
 * At the beginning of the game, while playing as Desmond in the hideout, he could see equipment shine blue in Eagle Vision. This indicated that they could be used for freerunning purposes.
 * Lucy made a reference to the ability by saying "Open your eyes, Desmond," when Desmond asked her how to find the sensors for the hideout's defense system, which she had tasked him to switch on.
 * In some memories in both Assassin's Creed II and Assassin's Creed: Brotherhood, water was shown to be glowing white like hiding spots when Eagle Vision was activated.


 * Assassin's Creed: Brotherhood
 * When traveling through Rome, Eagle Vision could be used to mark flags, feathers or treasure chests on the map.
 * While using Eagle Vision and roaming Monteriggioni as Desmond, a red trail was visible that led from the fountain with the Assassin insignia to the door of Mario Auditore's study. The trail was colored similarly to the blood glyphs of Subject 16, and appeared to be made up of many footprints.
 * An interview with Darby McDevitt and Falko Poiker explained that the trail was intended to help gamers find their way back to the Sanctuary, though its red color was a developer oversight.
 * When outside of the Animus, there was sometimes a pause that caused allies to glow gold for a few seconds.
 * Unlike in Assassins Creed II, enemies and allies did not glow their standard colors after they died, and would appear grey like civilians and inanimate objects.
 * When dressed as a Borgia guard captain in the memory "When In Rome," if Eagle Vision was activated, the armor would glow red, though Ezio himself would still be marked with blue.
 * Unlike Eagle Vision, Templar Vision marked targets with blue rather than with gold, since they were hunting other Templars and could be considered allies within a contained session.


 * Assassin's Creed: Revelations
 * During Ezio's pilgrimage and Altaïr's return from exile, ghostly images from Altaïr's past could be seen in Masyaf.
 * Unlike regular enemies, the paths of officials and the two guards accompanying them could not be tracked with Eagle Sense.


 * Assassin's Creed III
 * In the Grand Temple, Desmond, Rebecca, Shaun and William were not highlighted at all in Eagle Vision.


 * Assassin's Creed IV: Black Flag
 * Similar to the way it functioned in the original Assassin's Creed, Eagle Vision could not be used while moving in high profile.


 * Others
 * A mini-game in the Assassin's Creed room of PlayStation Home featured an Eagle Vision puzzle that, when completed, opened up the Hideout.
 * An issue of Nintendo Power stated that the Wii U tablet controller could be used as an alternate view for Eagle Vision in Assassin's Creed III, using the built-in accelerometer to control the camera view.
 * Ezio's Eagle Sense functioned in a clairvoyant manner.
 * Desmond, unlike his ancestors, didn't naturally possess a practical form of Eagle Vision, but rather he possessed it as a dormant trait, like most humans, despite having a significantly high concentration of precursor genes.
 * In Watch Dogs 2, another Ubisoft game, the NetHack ability is very similar to Eagle Vision.
