Vecna-loving demonic-pact Teifling Warlock
Every school for Wizards and Warlocks has at least one kid conspicuously sitting in the back, dressing in black all year round, and piecing together skeletal squirrel minions during lunch break. Mortiss was the kid that those kids picked on for being weird, morbid, and gloomy. He happily made a pact with a demonic entity to gain his magical powers, but seems to have been only middling successful with it, as his powers aren’t the most reliable (and his aim with them is frequently questionable). Mortiss is a founding member of the Hail Vecna Fan Club. He can invariably be found at the side of Jenny Sorrow (or hysterically wailing her name if something’s gone wrong).
