Arilemna is an elven demigod and an immortal servant of Jyggalag.
Background[]
Arilemna was a daughter of Auri-El who believed the Daedra so abhorrent and evil that they needed to be destroyed as soon as possible. To do this, she allied with one of them: Jyggalag. She believed the Daedric Prince of Order was the best chance for seeing Oblivion destroyed and saw him as the least repulsive of all Oblivion's denizens.
Serving Jyggalag has extended her mortal life far, far past what it should have been naturally. By 4E 201 she has lived for millennia. Unlike Rahn and Agemon, she did not vanish when Jyggalag was turned to Sheogorath.
She spent her time living among a crypto populations of Ayleids, who as Daedric worshippers did not reject her for her alliance with Jyggalag, as her own people had done. When the Ayleids went finally extinct, she dwelled by herself, alone in the forests of Cyrodiil. Numerous legends cropped up of an elven maiden who lived in the trees, appearing only to aid travelers or heal sick animals.
