I've made a couple of Gith toons on preview to check out the new race. However, the Character Builder doesn't allow for God/City options that align with the D&D canon for a Gith race toon.
Gith don't have gods, as I understand the lore - their only real allegiance is to either being a follower of Gith or enemy of Gith. And they certainly don't originate from the Sword Coast.
At the moment these elements have not been added to the character creation process. Will this be addressed in an upcoming update or are we supposed to pretend our Gith toons are natives of the Sword Coast, and followers of Gods the lore says they despise/ignore?
