Mira

Mira was a Gelfling who served as a guard of the Crystal Castle in The Dark Crystal: Age of Resistance.

While chasing down a Spitter who entered the castle in the first episode, she ventures into the catacombs underneath the castle where she is discovered by The Scientist and drained of her essence.

Her death is then blamed on Rian who witnessed her death, and eventually manages to steal what remains of her essence.
