Sadly, Joshua wouldn’t find much about the Sea of Stars except for a bunch of conflicting mythological and theological ideas. If Joshua were to ask the network, he would discover several oldbies who participated in a player-run event that took a visit to the Sea of Stars, and there might be a few meager reports of monsters claiming they have been there and seen all manner of beasts.

Beyond that, humans fill in what they don’t understand with concepts of faith, and each account will report a different idea about the Sea of Stars. Both of the gods have a limited understanding of the entity, themselves. You are welcome to make up all sorts of fun myths about it in your own time, but none of them will be the ‘factual’ coverage!
