Well Ziusudra and Utnapishtim would be the same person (they even have the same father in their respective myths) alongside Noah, Atra-hasis, and Deucalion; just like how Minerva is also Athena, Sulis, Saraswati, etc.

Ea-nāṣir

Are they mentioned at some point in Mirage or in the glyphs or am I missing something?

(Talking about Utnapishtim and Ziusudra)

It's gilgamesh, I remember from school

@Aiden Pearce Ashcroft None of them are directly mentioned. The Abstergo Employee Handbook which deals with Abstergo's attempts at having someone relive Arno's memories list some other suspected Sages including one from around 3000 BCE Sumer.

In the Epic of Gilgamesh where the eponymous hero goes looking for immortality he seeks out his ancestor Utnapishtim the hero of the flood myth who is called a "sage" and is himself immortal. Ziusudra is just a different tradition's name for the hero of the flood myth.

But the fact that Utnapishtim is specifically described as a sage in the myth most likely means he is the one being referenced by Ubisoft, not Gilgamesh.
