Sull is a semi-skilled fighter who works as a butcher in the South Ward of Waterdeep. After Icelin Tearn's great-uncle was killed by Cerest Elenithil's men, Sull agreed to take Icelin to Mistshore to hide from Cerest and the City Watch. He protected Icelin from Cerest and was seriously wounded in a battle with Cerest's henchmen. Later, Sull journeyed out of Waterdeep with Icelin and Ruen Morleth on a quest to find a cure for Icelin's spellscar.
Sull uses his butcher cleavers as his primary weapons.
Sull is a huge man with frizzy red hair and muttonchop sideburns.
