The Letters to the Guild of Mages is the name given to three letters written by the lich Erandur-Vangaril to the Mages Guild, with the first two crumpled and strewn about, while the final is complete on the desk. The three versions differ due to Erandur-Vangaril changing as he wrote the letters, beginning with most of his sanity and humanity intact, and ending as a complete lich.
