The Cult of Kosmos was a secretive cabal operating throughout and controlling ancient Greece and the surrounding regions. The Cult worshiped a deity called Kosmos. The Cult also operated in seven branches comprising several Adepts, with each branch led by a individual dubbed as the Sage.[2]

The main meeting place and hideout for the Cult was the Sanctuary of Kosmos, under the Sanctuary of Delphi in Phokis.[3]



The Cult of Kosmos was founded at some point after the meeting of Hermes Trismegistus and Pythagoras, which had led to the foundation of the Cult of Hermes. Disaffected with the Cult of Hermes' ways, a number of followers splintered from the group and formed their own collective; the Cult of Kosmos, led by the Ghost of Kosmos.[1]

Greco-Persian Wars

In the 5th century BCE, the Cult notably supported King Xerxes I of Persia during his conquests, seeing him as a means to unite all Greece as one under his one rule. In 480 BCE, when Leonidas I of Sparta consulted the Pythia about going to war against the Persians, the whole Cult confronted the Spartan King, warning him not to oppose their plans. Nevertheless, Leonidas chose to disregard their threats and fight against the invaders, an act of defiance which cost him his life.[4]

Following Leonidas' defiance, the Cult grew determined to wipe out his bloodline due to its potential for interference. In 446 BCE, through their manipulation of the Pythia, the Cult spread word that the youngest grandchild of Leonidas, Alexios, would bring ruin to Sparta and, as a result, the infant was sentenced to execution. Concurrently, Alexios' sister, Kassandra, tried to save her brother only to push him and the executioner over the cliff of Mount Taygetos, for which she was dropped to her death as well. The executions did not go the plan however, and both children survived. While Kassandra went into exile, her mother Myrrine took Alexios to the Sanctuary of Asklepios in Argolis to seek medical aid. The priests at the sanctuary, foremost among them Mydon, did what they could for the mother and child, but ultimately convinced Myrrine that it was best to leave the child to the mercies of the gods. She did so, and when she had turned her back to Alexios, the Cultist Chrysis took him under her wing, healed him, and raised Alexios like so many others to be a part of the Cult.[5] In doing so, she renamed Alexios Deimos, and the Cult saw him as a weapon rather than just another foot soldier.[3]

Peloponnesian War

Several decades later, the Cult orchestrated the Peloponnesian War in an effort to achieve control of Greece amidst the conflict of the country's two most notable city-states. At the same time, they discovered that Kassandra was operating as a misthios on Kephallonia. Initially, the Cult desired to have Kassandra killed but Elpenor convinced them to instead hire her and have her assassinate her stepfather Nikolaos,[6] to avert an immediate Spartan victory over Athens. But in doing so, Elpenor exposed the Cult's existence to Kassandra, who fought to stop the Cult's plans for control over Greece.

In 431 BCE, the Cult held a meeting after what had been a good while in the Sanctuary of Kosmos. Unbeknownst to them, Kassandra infiltrated their meeting.[3]

Foundations and Beliefs

The Cult of Kosmos were not polytheistic and had a deistic belief system. According to Aspasia, the nations in Greece were already chaotic and the Cult wanted to use a controlled war so as to create a clean slate on which to establish an orderly and unified Greek Nation, one where violence would be absent and the people could move towards a more rational and developing society, which would be built by the people for the people. Aspasia mentioned this would require a very wise and philosophical king.[4]

Some members of the Cult did, however, idolize and worship the people within the Bloodline, truly believing them to be actual demigods, such as Deimos. The members of the Cult soon grew chaotic and greedy and used the Chaos to earn massive amounts of profit and political power. Eventually this led to the Cult becoming corrupted with greed and personal gain, and these individuals enabled Deimos to become their violent leader. Aspasia, while still the leader of the Cult but unable to do anything to stop them, opted to use Kassandra to help her destroy the Cult so she could resume their original goal.[4]

  • κόσμος (kosmos) is a word that stems from ancient Greek origin, and it means both 'order' and 'world', mainly because the ancient Greeks thought that the world was perfectly harmonious and impeccably put in order.
  • While the leaders of the Cult were dubbed Sages, this dub does not have any connection to the Sages, the human reincarnations of the Isu Juno's husband Aita.
  • The cultists are wearing theatrical masks known from ancient Greek theater, and called πρόσωπον (prósōpon), which literally means 'face, mask, visage'.
  • It's mentioned that the bandit group known as The Dagger was better organized, connected, and funded than the common run of the mill bandit groups, but what their connection to the Cult of Kosmos is left very vague in-game, if there indeed was ever even meant to be one.[8]
