[@PerseusArchean] Maaaaan, I dont know anything about the underworld.
Ha! Just kidding. I still read up on the concept of death and 'hell/underworld' in any form. Tis muh pleasure.

Did you know the underworld is actually capable of a paradise? Tis true! The souls who attain a status of praise from the gods is granted the right to be reincarnated. If they die in 3 seperate lives with the praise of the gods, they are brought to an island within the underworld for eternal happiness! 

As for the gods coming back, well, I'm still pondering how without stelling on you and cuccos toes plot-wise. PM me some details and ill whip up a tasty post for all to enjoy!
Also PM me everything that is going to happen. Because reasons. Thanks
