The Cult of Kosmos was a secretive cabal operating throughout and controlling ancient Greece and the surrounding regions. The Cult worshipped 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.



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.[1]

Greco-Persian Wars

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. 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.[3]

Following Leonidas' defiance, the Cult grew determined to wipe out his bloodline due to its potential for interference. Through their manipulation of the Oracle of Delphi, 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 Argolis to seek medical aid. The Cultist Chrysis faked Alexios' death and thus the Cult raised him as a weapon called Deimos.[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, to avert a immediate Spartan victory over Athens. But in doing so, exposed the Cult's existence to Kassandra, who fought to stop the Cult's plans for control over Greece.[3]

Foundations and Beliefs

Much like their Egyptian counterparts, the Order of the Ancients, and their future incarnations, the Templar Order, the Cult of Kosmos were not at all 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 there would be no more violence 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.

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 had soon grown chaotic and greedy and used the Chaos to earn massive amounts of profit and political power.

  • 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'.
