I was wondering if there was a way for 3rd circles to survive there oversouls going neverborn
And them essentially getting whispers N/A because of it.
Their existence causing dead neurons to fire in a similar way that electrifying a corpse can cause it to stand, trying to pump necrotic essence into a being never meant to handle it, making them shun the underworld even more than the other residents of Malfeas. Desperately avoiding anything to do with it to avoid aggravating the issue. Risking everything to destroy all records on how to summon them from a prison where they are safe, unable to be bound as there patrons never signed onto the surrender oaths, these devas being the only willing residents of hell.
But because of there connection, they contain some of the greatest secrets of void circle necromancy aligned to their dead patron, but the process of accessing that knowledge killing then slowly driving then to become more like their murdered siblings.
An aspiring and powerful necromancer need only capture a prince of hell and coerce there secrets to attain true power. Somehow forcing this powerful entity to sacrifice there lives, to an existence of unending pain, to learn what none before them has, or could be learnt by other methods.
