It appears to be a vague outline of a strange-looking man's face.
Claimed by his followers to be the First and most powerful god, Dentin is now known as the god of Creation and Building. Its priests construct massive architectural wonders in Its name, and their teachings revolve around observation, analysis, construction and progress. Dentin also does not tend to interact with mortals, and has great tolerance for blasphemers - meaning that mortals typically speak their mind about Dentin without fear of retribution.
Dentins' relation to the other gods seems open to debate - while clearly a power to be reckoned with, other gods often appear to be in positions of greater power within the Pantheon. Rumor has it that Dentin does not usually get involved in Pantheon affairs except to balance out gross injustices against mortals or gods.
The tolerance typical of Dentin is limited however, as evidenced by the great wars of a thousand years ago and the Mud University records of three hundred years ago. In both cases, groups of mortals (and gods) came to challenge Dentin directly for control of Creation. The ruins of the broken half of the University serve as a stark reminder that for mortals at least, challenging Dentin is not a good idea. The horrors of the Eaters clearly show that what Dentin has created, he can also destroy.
