The Fallen Ones

Beings who used to have immense and incomprehensible power, but had it stripped away when they fell away from the directive of the universe. Some don't even come from this universe, or even any that the "Lost Gods" would even recognize... All of these beings even had their names stripped from them, so that they would never gain power from their names again; hence why each of them has a name that begins with a "Y", as that is symbolic for them splitting from the other Celestials.
