I'm just gonna start redirecting people to the character creation thread for the creation rules, and to the OOC thread for questions beyond that, because honestly I'm answering a lot of questions here that are already answered in the creation rules.

To answer @karsusthemad, Lasombra Antitribu are fine, because they're mechanically identical to Lasombra except the Sabbat don't like you, though it's worth noting that the PCs aren't affiliated with the Camarilla by default. Players start effectively Independent or Unaffiliated, due to the circumstances.

For @ErebusVonMori, Mytherceria is specific to a clan that isn't permitted in the game, so no that one wouldn't be allowed.

For everyone, please direct further questions to the OOC thread in the game forum. Makes it much easier for me to track things.
