Nahsk was an associate of Morn's, involved in the Lissepian Mother's Day Heist.

He and his brother, Krit, would later attempt to find the thousand bars of gold-pressed latinum stolen in the heist. Nahsk was the "muscle" and his brother was the "brains" of the duo. They would double cross the others who participated in the crime, but all were arrested ultimately by the authorities. (DS9: "Who Mourns for Morn?")
