[@Rondo of Blood] Well [i]someone's[/i] been doing research. I don't think I've mentioned the Cult of the Dragon at all. I will warn you, this sort of metaknowledge will need to be kept on the down-low - however, you are not incorrect that the Cult of the Dragon is involved, and at least one other player character knows of their existence. However, I will say that being a cult leader is not very feasible at first level. You might have been a low-ranking member of the cult, but we'll see.

I can provide a couple of things that tie your character's history more closely to the Cult's, too - one that might make a little more thematic sense than 'cult leader'. It's up to you.
