One of Bar'T'Rd K'Lns' three Kobold squires alongside Oono and Dozz, Trez serves valiantly as part of the Order of Society. He and his two siblings spent much of their time prior to joining the team disguised (badly) as an Elf using a trenchcoat - according to Dozz, this was originally because many bars in Balla tend not to serve Kobolds. This was something that Bar'T'Rd found 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. While the injury itself could be healed to the point where he could fight again, the damage to his ribcage was extremely severe and his ribs broken in such a way that they didn't fix themselves correctly, giving him a slightly wheezy tone to his speech. With note to this, he wears a far heavier breastplate than would be expected with the style of armour he tends to wear to help prevent further damage.
The youngest of the three siblings, Trez is by far the most intelligent and magically gifted, though not necessarily the most sensible. He tends to be the quietest of the three as well, usually hiding behind his two older siblings, and tends to let actions speak more than words. He can be somewhat nervous as a result, and tends to take obsessive care of his weapons and armour.
