Ubtao

Ubtao is a deity of Chult known as the "Dinosaur Father". He abandoned the people of Chult due to their constant warring, and 9 trickster gods took over in his stead.

Strix met a man named "Ubtao" in the nightmare maze that Dendar sent her to. This Ubtao claimed to have been the owner of a shop in Sigil, and to have no knowlege of being a deity or of the trickster gods.
