Sor'unel is the son of Lord Eridion Aeldaris and Naaniel Cirenden. He used to be a member of House Aeldaris, known at the time as Sor'unel Aeldaris, until he petitioned to have himself attainted, stripping him of his name and claims to his family's ancestral home. Shortly after his birth he was given to the Psijic Order and placed in a time bubble until (date), when Psijic monks removed him from his stasis and raised the boy on Artaeum.
Sor'unel joined the Thalmor and devoted himself completely to their ideals of Altmeri supremicism and purity.
