Aiimus, once a captain in the Argoan army, heard Garfife's calling, and now stands guard as the caretaker of an ancient, almost forgotten temple that houses an incredible secret. Endowed with incredible fighting prowess from the Maker, he is a fair man, but will dispense punishment harshly when needed.

Aiimus is a stoat by summer, but when the winter months roll around, his fur changes to the nearly pure white of an ermine. He hates being white, so decided to be captured in his summer form instead here.
