Nothic

s are one-eyed creatures drawn to places with arcane knowledge.

Description
Nothics are humanoid in shape, with blotchy gray skin, backs covered in spikes, and clawed hands and feet. They often collect magical items. Nothics have one large yellow eye in the middle of their head, no nose, and many teeth.

In D&D lore, nothics are former wizards who, after spending their lives trying to delve into arcane secrets, were cursed by Vecna. They seek out places where arcane magic is learned or practiced.

While scouting ahead as Vox Machina made their way through the Crypts of Thomara, Vax'ildan saw a lone nothic eating what appeared to be the limb of an animal or person. Vax killed it with a single attack. When he looted the body, he found some bones, half of a book in a language he didn't recognize, a dagger, a spyglass, and a bronze key.
