Seal was a young scholar and former Malazan Army healer with curly black hair. His warren was Denul. After his military service, he retired to Malaz City and lived in a whitewashed brick and timber house with his young son, Jonat. He was also a D'bayang addict.
His great-uncle had served in the Grist-Khemst border wars and Seal kept his old armour in an iron-bound chest.
On the night of the Shadow Moon in 1154BS, he gave his great-uncle's armour to the veteran Temper. Later that night he likely saved the life of High Mage Tayschrenn's bodyguard Hattar after a disastrous fight at the Deadhouse.
