*Worf is the first Klingon to serve aboard a Starfleet vessel. He was orphaned after Romulans attacked the Klingon outpost at Khitomer. Adopted by human parents Sergey and Helena Rozhenko, Worf was raised with a foster brother on the farming colony Gault. Assigned as a Lieutenant Junior Grade to the Enterprise, he became Chief of Security after the death of Lt. Natasha Yar. The Klingon family Duras framed and ostracized Worf's father in an attempt to seize control of the Klingon High Council, but Worf cleared his family name with the help of Captain Picard and the U.S.S. Enterprise. *Source: Back of card
