As of Day of the Huntress, day 19 of the month Koaratos in the year 5119:
You see a man in bleached white armor that is covered in blood red runes and seems to shift as if something moves beneath it. A huge bleakstone scarab carapace serves as the breastplate of the man's armor. His eyes are hollow and a dark, dark grey. Scars in the shape of a crown encircle his bald head, but rivulets of glistening blood flow along the jagged mutilations in his skin. His flesh is pale and as white as death.
Disean is the son of Sir Thadston Andrews but was raised by his mother, Saraphene, and her new husband, Lord Ambrus a Paladin of Koar. Disean was appointed by Prelate Chaston Griffin as an acolyte in the Temple of Koar inside of the capital of Talador.
Eventually, he became enthralled by Griffin and, because of his connection to Sir Thadston, Chaston converted Disean into one of his Blameless. In the end, he fell victim to Raznel who abducted him after the fall of Chaston and his whereabouts were unknown for some time.
For most of 5118, Thadston spent time with Casiphia searching for Disean, and hinted to once having found him but Disean, now twisted by Raznel, used a cursed blade to wound Thadston. Disean is still at large in the service of Raznel.
At one time, Disean had romantic feelings for Casiphia.
