Physical description

Huginn and Muninn False Form

Muninn (left) in his False Form with Huginn.

In his false form, Muninn appears to be a common raven but with an eyepatch covering his left eye.

In his true form, however, Muninn is a large navy blue raven with silver highlights. He has straight horns, a smooth beak and three taloned claws. A crescent symbol covers the left side of his face where his missing eye should be and a half moon symbol lies on his forehead. He wears a beaded necklace and beaded bracelets on his claws as accessories. Compared to his brother, Muninn is darker, more feminine and slightly smaller.


Like his partner, Muninn is calm, cool and collected, usually having to calm down his older twin brother, Huginn. He is very loyal to his brother, and faithfully follows along with his plans, which sometimes gets them into difficult situations.
