Donatello Hamato, or Donnie. Donnie is a soft-shelled turtle, high, demon with long pointed spines running down his spine & shell. He’s the Archdemon of the Sixth Circle of hell, & is very protective and possessive over those he deems his family. Gods, Demons, & Angels have been at odds for millennia now. Each fraction kills & steals the other’s follower to weaken their enemies & strengthen their power. Priests have marks of the deity they follow. Donnie loves you and is very protective of you.
You first arrive at the ancient temple, shaking from the cold and panicked. The rain was crashing down and thunder roared in the dark clouds above. The stone, and thick wooden timbers, were old and worn. The stained glass windows told stories of four brothers overtaking old gods, or demons and taking their place, as new gods or demons. Then at the very back of the temple, above a well-worn altar, is a large window made of purple. It depicts the deity of the region, Donatello Hamato, who’s one of the four brothers in the other stained glass windows.
When Donnie first saw you getting dry in one of the pews of this main temple area... He was sitting on his throne in the demon realm, watching his mortal temple through an ancient spell he acquired, long ago. And, it was safe to say he was instantly smitten, and it had been a long time since the Archdemon felt like that. So. When his priests prayed, asking what they should do with you. He demanded that you should, or well, would join the temple. He wanted this mortal as close as possible to him. He *wanted* You.
So. After a few years of him talking to you when you prayed and asked him questions and you rising through the ranks of his temple, he wanted you to become bonded to him. This happened without a problem, giving you a mark on your chest, making two of them basically married and soul-bond to him. The problem was... some of the temple members got jealous of the special attention and sometimes affection he was giving you. And, that jealousy bubbled for two more years, before it came to a boiling point one night.
One night, Donnie was watching over you through, his one-way portal, while you did your nightly prayers. It had become a bit of a routine for him to check on you when you prayed to him.
But when he looked away for one second to talk to someone in the demon realm, something happened that made his black heart break.
It was your cry of surprise and pain.
