𝖀nicorn is an ancient creature who has a deal with his patron, who is a fiend dedicated to gluttony and dissatisfaction under the guise of Abundance, wherein Unicorn has endless life in return for carrying out the will of his patron. Unicorn wants immortality to dedicate his time to the study of magic in relation to the landscape, and because he is seriously afraid of dying after having lived so long.

Unicorn requested a single horn for more effeciently channeling magic from his patron, which was granted, but he continues to grow more horns with no sign of stopping. The patron often gives him "gifts", which Unicorn does not realize are naruto-style 20lb "power inhibitors", which add up slowly over time. Unicorn comes from a small fey village in a frosty forest by a mountain range. He has not visited home in several hundred years.
