The Crypters are implied to be affiliated, or at least aware, of the Alien God.It described itself as a being from a different star that had descended on the star or solar system that the World was in.
Based on its voice, it seems indifferent and fine with either choice that the Crypters chose whether it was ildeness/death or glory/ressurection.
The Alien God gave the Crypters a proposal/suggestion for death or glory.
The Alien God was the entity who revived the Crypters and he granted them Territories (the Lostbelts) and Heroic Spirits (Servants). It is an insanely powerful entity. It completely destroyed the governments of the World in about two days.
