The Teacher (? AC – 424 AC) was a male Human who was a member of the Faceless Brethren, the followers of the long-dead archmage, Maladar an-Desh. Originally hailing from the Rainward Isles, he met The Master and the others who would join the Faceless Brethren on the island of Suluk. He would then discard his identity and became known as The Slayer. Like the other followers of Maladar, he bore numerous self-inflicted wounds, and had carved away large amounts of flesh from his face, showing the bone underneath. His face was little more than a leering skull, with blazing eyes, a black tongue and long teeth.
In 424 AC, the Teacher and the rest of the Brethren had setup their headquarters at the Temple of Akh-tazi in Neron. They plotted a means to recover the Hooded One to enable the return of Maladar. When the Brethren attempted to sow discord through the Imperial League, The Teacher was tasked with corrupting the Uigan and coercing them into raising an army against the League. The Teacher began to teach the sorcerous arts to Chovuk Tegin, who became his willing servant and also shortly after the Boyla of the Uigan. Chovuk indeed raised the Uigan forces against the League, resulting in the Battle of the Run. The Teacher was also responsible for travelling to Lake Starshimmer in the Marak Valleys and charming all the Marak Kender he could find. He then used his magic to change them into Shadow-Fiends, soulless servants of the Faceless Brethren.
It was at Lake Starshimmer, that Barreth Forlo and his companions came across The Teacher as he was converting more kender into shadow-fiends. The companions rushed the sorcerer and struck off his arm. They interrogated the fiend whilst he was bleeding to death, and then Hult beheaded him for the crimes he had done against the Uigan and his master, Chovuk Boyla.
