Sekir

"Sekir, Sekir, Sekir. A man once made of flesh now made of tar." - Hymns of the Will
Sekir is the god of death and overseer of the Depths. It's not his duty to torture those there, but rather to just make sure they get there and aren't stuck somewhere in between. Rarely, as said in the texts, does Sekir interact with people in the Depths. Some interpret this as proof that he spends most of his time on earth, tempting humans to commit acts of sacrilege.

He is different from the other dieties in that his appearance was never explicity stated in the old texts. In ancient manuscripts, it was said he was the first human created from the blood of the world, but corruption manifested inside his greedy body, making him more powerful than Amos could have imagined. Deciding to lock him away, Amos and Aktorak trapped him inside the Earth to rule his own hell, the Depths.

His symbol is an eye since multiple times in ancient scripts he is described as all seeing and being everywhere at once. People call it the Sekir's Eye and being caught carving, painting, or drawing it anywhere can get you in a lot of trouble.

Flesh priests are devout worshippers of Sekir, although they do not follow the Will of Amos the same way its worshippers do, they have their own religion centered around him.
