His backstory is under writing. He does have five small horns (like his mother https://i.pinimg.com/736x/5f/38/21/5f382163679d4c009395fe82e8023e6f.jpg) protruding from his forehead, but he usually keeps them covered to avoid people judging him for his fiendish blood.

The Moon domain made his fur silver, and the Trickery domain allowed him to change his form. He prefers to take on the visage of a many-tailed Kitsune (7-10 tails, depending on his magical power), after the fortune teller who he learned from, though he also likes being a silver-haired elf, especially around Midi. While in these forms, instead of his horns, he has a series of moon phases across his temple where the horns normally would be - waning crescent, last quarter, full moon, first quarter, and waxing crescent, looking at him from left to right.

Enamored with Midilyen.
