Elosai was exiled into the Thousand Needles because she had been researching for a cure to the blood elves' magical addiction. In the end though, her cure failed; instead of curing her addiction the tonic accelerated it, which caused her to become a Wretched. She was understandably upset by the effects of her concoction and despaired that her years of research had been for nothing. She miserably wondered whether the other blood elves were right and that their magical addiction is something they must live with- that it cannot be overcome.
She was killed during the Cataclysm, presumably by the invading Grimtotem tribe. Her corpse is in the form of a wretched, confirming that her transformation was one-way. She is found still holding the vial that she drank from.
