Eir is an Asgardian maiden and talented physician.
When Frigga discovered that Loki was alive after falling into the Yggdrasil itself, and that he intended to conquer Earth, Odin sent Thor using dark energy to retrieve Loki, since the Bifrost Bridge was destroyed. However, that process left Odin in a very weakened state, and he was put under Eir's care.
When Jane Foster became infected by a primordial force known as the Aether, she was brought to Asgard for treatment. Eir was then called upon to treat Foster, although she could do little to treat the human. However, she was able to provide information about the nature of the infection through use of the Soul Forge. She initially ignored Foster's attempts to understand Asgardian technology; she was surprised and somewhat impressed when Foster correctly guessed the Soul Forge's basic functions. Eir was later present at Frigga's funeral.
