Among several Klingons, two Evora are seen passing in front of the gates of Little Qo'noS. These chunky little aliens were first introduced in Star Trek: Insurrection, when Captain Picard and the crew of the Enterprise-E welcomed them to the Federation with beadwork and the customary greeting, "yew-cheen chef-faw".
