He is the Precious Night Turkey and a God of Mystery.
It is a mystery we have been unable to unravel. There is a picture of him in the Codex Borbonias that is so utterly weird it must be seen to be disbelieved. In the midst of seemingly undecipherable symbols he is dressed in a turkey suit and seems to be vomiting into a large pot.
We may need to come back to this later, but not without a stiff drink or two first.
