Mjerdër is a very old demon that thinks she is royalty. She is considered very dangerous, because she is mentally unstable and sometimes uses very powerful magic without really meaning to. Emi is in charge of keeping track of him, as well as keeping him away from blood, which is the source of his magic. Mjedër and Orna share a relationship of sorts that certainly couldn't be classified as romantic, but is more than just sexual. Mjedër loves being pampered. Whether presenting as male or female, they value beauty.

Shapechanger: Mjerdër is very fluid in their gender and can change from female to male or anywhere between. All of their features, such as horns and markings, remain the same.
