I remember reading a post by someone a few days ago asking which awnshe had preists in the books so here goes.

With priests mentioned in the books

The kraken
The Sphinx
The Serpent
The Warlock

Known to be worshiped as gods but never have preists mentioned about them

The spider
The white goblin
gorgon(unusual case with the hand of azrai not enough is mentioned about it but it does have preists)

I might have missed some
