Kosh uplifted the Wortl 39 million years ago. As new citizens they helped coordinate the final hundred millennia of the Union for Self-Esteem, gaining respect for their earnest efforts. Wortl have a reputation for patience and they still have great influence on their mighty clients, the Thennanin.

They are 2.5 metres tall bipeds with slim cylindrical heads. Faceted eyes bulge from either side, two-thirds of the way up their heads. The neck features gill-like breathing slits. Hands are rounded cones with eight mini-finger tentacles at the ends of multiple-jointed arms.
