Aging Klingon adviser to the House of Kozak who helped Grilka defend her family's interests on Qo'noS.
Tumek is an elderly Klingon who serves the House of Kozak as an adviser in The House of Quark. After Kozak's death, he stands with Kozak's widow, Grilka, as the house faces ruin at the hands of its rival D'Ghor.
Tumek is present when Grilka brings Quark to Qo'noS and marries him to protect the house, and he watches the Ferengi's unorthodox defense of the family before the High Council. Joseph Ruskin played the role.
