D&D. Dungeon Academy. No Humans Allowed!

Welcome to Dungeon Academy, where monsters and creatures train for the dark world that awaits just beyond the Dungeon walls. But Zellidora 'Zelli' Stormclash wasn't a monster or a creature. She was something far worse. Zelli was a human.
Disguised as a minotaur, Zelli keeps to herself and does her work. While in class, Zelli learns of the great human adventurer, Allidora Steelstrike, who oddly resembles her. Could Zelli be - a Steelstrike?
Seeking answers to her true lineage, Zelli embarks on a dangerous adventure. But she won't be alone. A vegan Owlbear, a cowardly Kobold and a shapeshifting Mimic who only transforms into nice things will join Zelli on her quest for the truth. And who knows, perhaps these monstrous misfits may discover truths of their own…
