The Isu Era was a period of time marked by the existence of the Isu as the dominant species on Earth.[1] What time period preceded the beginning of the era (c. 77,306 BCE) is unclear, but the Isu species itself at least had a presence within the border of modern-day Jordan around 77,986 BCE, roughly the equivalent of -680 Isu Era.[2]

Atlantis before its sinking
- Poseidon took control of the city of Atlantis from his son Atlas, and let Atlas and his other sons serve as archons.[8][9]
- Hades abducted Persephone and forced her to become his wife, with the consent of his brother Jupiter.[10][11] He imprisoned Persephone in an area of the Underworld that she reshaped as Elysium, which Hades allowed her to rule alongside her friend Hekate.[12][13]
- The Sister Realms were formed between Atlantis, ruled by Poseidon; the Underworld, ruled by Hades; and Elysium, ruled by Persephone.[12]
2194 IE[]
- Day 6: The human workers from a construction site in Qobustan, Azerbaijan were reassigned to the sanitation of a nearby lake.[14]

c. 2200 IE[]
- The Staff of Hermes Trismegistus was forged in the late "Isu Singularity Age".[16]
c. 2220 IE[]
- Juno recovered the prototype Shroud of Eden housing Consus' preserved consciousness.[17]
Unknown[]
- Poseidon granted Juno and her husband Aita access to Atlantis, where they secretly started the Olympos Project, in which they experimented on humans and created monstrosities.[18] Poseidon banished them from the city back to Feyan and outlawed human experimentation in Atlantis.[19][20][21]
- A summit was held by the Sister Realms through a delegation of Atlantean embassies regarding the findings of Atlantis' Solar Dynamics Observatory and the threat of solar instability. Hades was the only leader to attend, but embraced the prospect of annihilation.[22]
- Poseidon, on the advice of his dikastes Aletheia, destroyed the city of Atlantis due to recurring upheaval and friction between its Isu and human populations, by sinking it into the ocean.[19]

Adam and Eve fleeing Eden with an Apple
- Adam and Eve, two Isu-human hybrid slaves, escaped from the city of Eden with an Apple of Eden.[23]
- Humanity rose up in rebellion against the Isu,[24] prompting a ten-year long war.[25][26] The Isu Saturn, Juno's father, was one of the first victims of the conflict.[27]
- The Father of Understanding Jupiter, the Mother of Wisdom Juno, and the Sacred Voice Minerva retreated to the Grand Temple to find a solution from the impending solar flare, ultimately trying six unsuccessful options.[28][29][30]
- Balor defeated Cú Chulainn but was struck by Cú's spear Gae Bolg, which became lodged into his back. Later, the Isu Odin faced Balor in combat and claimed the Gae Bolg following his victory.[31]
- Odin imprisoned Fenrir, the son of Loki and Aletheia, after it was calculated that Fenrir would kill Odin during the impending catastrophe.[32]
- Baldr, the son of Odin, was fatally poisoned with mistletoe by Loki in retaliation for the imprisonment of Fenrir.[33]
- Aita volunteered as a test subject in an experiment to transfer Isu consciousness into human bodies, though his mind swiftly deteriorated.[34][29]
- Juno developed a seventh solution to escape annihilation, a serum that would allow the Isu to be reborn as humans. Due to worries concerning the pollution of the human genome, the solution was abandoned by Jupiter and Minerva and the serum was locked away.[35]
- With Juno's aid, Odin stole the serum of the seventh solution in order to survive the impending catastrophe. Using the serum,[35] Juno secretly added samples of Aita's genetic code into the human DNA allowing him to be reborn in humans as Sages,[36] after which she agreed to end his suffering.[29][36] Vejovis also took advantage of a similar method to develop Sages of his own self.[37]
- Juno secretly tampered with the Eye built by Minerva to prevent humanity from inheriting the Earth. After her treachery[29] and role in Odin's theft of the serum[35] were discovered, the High Council stripped her of her title[38] before Minerva and Jupiter digitally imprisoned her consciousness inside the Grand Temple.[29]
- After being gravely injured, Loki helped Aletheia upload her consciousness into the Staff of Hermes Trismegistus, hoping for the two of them to reunite after the impending catastrophe.[39][40]
2306 IE (c. 75,000 BCE)[25][]

Earth after the Great Catastrophe
- Minerva made preparations for another solution involving the global aurora borealis device to be tried during the next solar cycle, hoping that it would be successful without Juno's influence.[29]
- The Great Catastrophe occurred[15] when a solar flare struck the Earth. Less than 10,000 humans, and far fewer members of the Isu, survived the cataclysm, bringing an end to the Human-Isu War.[24]
- As the Great Catastrophe struck the Earth, Odin, Týr, Thor, Freyja, Idun, Frey, Sif, and Heimdall used the serum to upload their DNA into the supercomputer Yggdrasil to be incarnated as humans in future generations, before meeting their inevitable doom. Loki killed Heimdall before he could leave Yggdrasil's chamber and secretly used the serum to be incarnated as well.[41]
- Three months after the Great Catastrophe, six Messengers recorded reports over two weeks' time for Layla Hassan before storing them in vaults scattered around Egypt. In order, they were the Amun Amunet messenger at Oun-mAa Niye Ressoot,[42] the Nomarch messenger at Seshem.eff Er Aat,[43] the Khufu messenger at Khesesh Em Sesh Em Eeneb,[44] the Khnum and Hequet messenger at Eeyoo Sekedoo Aat,[45] the Seth Anath messenger at Qeneb.too Kah'Aiye,[46] and the Sphinx messenger at Eesfet Oon-m'Aa Poo.[47]
Post 2306 IE[]
- In the wake of the Great Catastrophe, humanity and the Isu started working together to rebuild civilization.[24] The Isu influenced human civilizations' early stages and would subsequently come to be revered as gods by the humans.[24][48]
- The last Isu died roughly 100 human years after the catastrophe, according to estimates made by the Assassins.[49]
