Ctein

The Great and Mighty Ctein ruled the Jellies for centuries from its rocky mound amid the Abyssal Conclave in the oceans of Pelagius. Huge and ancient, Ctein survived numerous challenges to its leadership during the Sundering—the great civil war of the Jellies—and grew to enormous size. It had dozens of tentacles, thousands of eyes, and buried within the center of its carapace, a functioning fusion reactor that powered the creature’s weapons, defenses, and communication systems. Not a being to lightly cross, it was more than the mental equal to even the largest human ship minds.
