Sokor was a shipbuilding company founded on Qo'noS in the 2340s, during the economic boom years of Chancellor Kravokh's reign. Sokor failed after a short undetermined period, and was forgotten by the 2370s.
One of Sokor's potential investors were Gannik, but he was convinced by an associate, L'Kor, to instead invest in a rival company, Turok. The more immediate failure of Turok led to a decades-long conflict between the two men and their families. (KE novel: A Burning House)
