I personally do not support this theory. But it can be justified. That is, the Cyric is a mad deity, and his domain is deception. It is possible that he tricked the goblins, drow and other followers into posing as both a woman and a man. The use of the symbols of the Dead Three can be justified by the fact that initially Cyric usurped their orbs when he killed Leira and making himself the God of Deception, Murder, Strife, the Dead. By the way, it seems strange to me that Cyric is not on the list of deities. Perhaps this is due to the fact that the game is in EA, but it's still weird.
Yes, this where I started; but I am also now under impression that I understand what Larian and WotC wanna do... and how it's going to meld into current 5e handbooks.
Cyric was supposed to rise in power around the time of BG3 and it's not adressed in the books so far. I assume it's going to be addressed in the game. Specifically if you don't keep certain someone in check.
