Basically, characters left the Nexus and went to the Happyverse, a happy place that isn't the nexus.

Also, Eve is still the only PC harpy that fights for heaven, not including Syphax. Maceroy fights for the Machina (and is Eve's father from a forever ago), and Atarah fights for Hell.

Edit - Whoo boy, that's an awkward family reunion.
