Pssst....Hey Cleric. Might I put in a slight request involving the timeline. Namely moving back the Voidlings "creation" back a little. Given their general theme/purpose I realize it wouldn't make sense for them to have spawned into being after the creation of the universes was complete. (Perhaps during the process....maybe even post Xenos prototype universe.)
(Heck, could even go a step further and says Xeno cutting a prototype universe out of the void was the exact thing that kickstarted their creation. *goes into ponder mode*)
