One of Bar'T'Rd K'Lns' three Kobold squires alongside Oono and Dox, Trez serves valiantly as part of the Order of Society. He and his two fellow Kobolds spend much of their time disguised (badly) as an Elf using a trenchcoat, something that Bar'T'Rd finds both bewildering and exasperating. Nevertheless the three of them are steadfast in their dedication to the Order.
The three were severely injured during a battle with a group of undead Giants during the Balla Incursion. Trez came off worst of the three, suffering severe injuries to his upper torso which left him incapacitated for some time.
