Harengon

Harengon are a remarkably resilient species, who's existence hinges on the Fey Wild. The majority of Harengon live predominately off the material plane, preferring to reside on the plane of Wood or the Fey Wild. Centuries of cunning and magical bargains with Fey are responsible for Harengon defying evolutionary odds and becoming the way they are today.
They are naturally blessed with bountiful energy, and an innate sense of self preservation. Harengon are incredibly diverse as things go. Their rodent heritage enables them to reproduce exceptionally fast. Thusly many variations exist spread across the cosmos. Typically a Harengon will develop convergent with near by fey becoming similar physically and culturally to the design of whatever Archfey has touched their life.
