Alessoria was one of Netheril’s most accomplished assassins. She was completely loyal to Prince Clariburnus. She was part of the expedition that followed the Northern Five to Ellyn’taal to discover the fate of Ioulaum, the first of ancient Netheril’s archmagi. The Prince hand-selected her to ensure that the expedition did not deviate from his will. She was killed when Fulminorax attacked and the Northern Five betrayed them to the Thayan blue dragon.
