Krit is one of two brothers who arrive on Deep Space 9 after Morn's apparent death, claiming a share of the fortune he left to Quark as former partners in a famous robbery.
Krit appears in the sixth-season episode Who Mourns for Morn?, played by Brad Greenquist. He and his brother Nahsk turn up in Quark's quarters once word spreads that Morn has died and left everything to the bartender, and Krit, the talker of the pair, explains that Morn owed them money and that they intend to collect.
The brothers were in fact Morn's accomplices in the Lissepian Mother's Day Heist, in which a thousand bricks of gold-pressed latinum were stolen. So were Larell, who poses as Morn's former wife, and Hain, who poses as a security officer. Each wants Quark's help in cutting the others out.
When the latinum is finally retrieved, the four turn their weapons on one another in a cargo bay while Quark hides, and Odo arrests them all.
