At the creation of the world (Tyria), I would say the gods were Dhuum, Abaddon, Balthazar, Dwayna, Lyssa, and Melandru. I say this because the scriptures of Grenth don't even come until late A.E, which may suggest he wasn't around, and also, Doric did not encounter Grenth in Arah. While it has been suggested he simply was not there (was in Cantha, or other such areas), it may also be likely that he simply was not a god at the time. Also, the Ritualist profession would have originally worshipped Dhuum, before Grenth "reformed" the profession. It says they worshipped and drew power from the spirits of their ancestors. Even if they aren't directly worshipping a god, they are indirectly drawing power from the one who holds swaye over their ancestors.
