Now, we know by the current situation that half of Illith was bound underground ( I think that's right ) Half was taken by Keph, and then keph shattered, and had her shards carry on with the duty of sealing Illith, while the other half I think escaped, but was severely weakened and defeated soon after.

Slowly, the Vernal Gods succeeded in their campaigns. First, Illith the Leviathan was frozen in the icy depths of the ocean.

Could someone explain this for me, How this happened during the vernal wars. Am I wrong? Missing something, or did I find a mistake?

Edit: The Site histories also say that Ketheru was the most powerful, but wasn't he Second to Illith until Illith got messed up?

Half was trapped by Keph, in UV, then the other half escaped and ran away to fight again another day, which was then trapped in the Vernal wars. The second half wasn't killed in the Elder wars, that's where you went wrong.

During Elder Wars, Illith was cut in half by Keph. Half was trapped by Keph/kephera and the other half was later trapped by the Vernals in the Vernal Wars. This half, the serpent, later came to suck all the essence of Kethuru (Taint).

Illith was the strongest prior to the Elder Wars, but with her being cut in half as well as Kethuru consuming so much essence, he was able to become the mightiest.

Ah, for some reason i was under the impression that Illith was killed by other Elders after being sliced in half
