Artist's description:

Onyx Daze Pie | he/him
Son of Maud Pie and Starlight Glimmer, Onyx is an aloof and stubborn, sees himself as something of a puritan, believing unicorns should only dedicate themselves to the study of magic. He’s is covered in scars from spells gone wrong. He degrades those who worsen his studies, and ridicules unicorns who use their magic for trivial purposes. He attended the School of Harmony to little affect, gaining acquaintances but nothing more. He’s protective of his little sister, Stalla Balas Pie. Most of the time you will find him locked away in his room, mastering a new spell.
