Erthalif

Erthalif was an high elf mage that died three hundred years before the Third War. Aegwynn was given access to his redoubt after his death. It took her and Erthalif's old staff ten weeks just to organize the scrolls, scrub away the desiccated food and drink, and chase off the vermin. The Guardian then found notes taken by the legendary elf wizard Kithros in the library and use them to write a new banishment spell.
