Childe of Zillah. Ilion is the antediluvian who begat the Learned Clan, the Brujah.
Developer of the time shifting power of Temporis.
Diablerised by his childe Troile.
The discipline of Celerity was reserve engineered from what Troile learn about Temporis.
Ilion is stuck in torpor of sorts. After creating Temporis and mastering it, he became stuck in a time loop, but without the time loop he would have suffered final death at the hands of his childe. The time loop allows him to watch the Jyhad and examine history, analyze the other 3rd and second gens.
