Trolk was a male Klingon who worked as a construction worker in the city of Krennla on Qo'noS in the mid 24th century. His co-worker, Ch'lan, often described him as the worst worker at any construction site. In early 2376, the company Trolk worked for went out of business, and he was left unemployed. Trolk was also a longtime patron of a local tavern, Kravokh's Beard. (KE novel: A Burning House)
