In late 2369, she was part of an away team sent to Ohniaka III, to explore and answer a distress call. Assigned to search the north wing of the outpost with Worf, she was killed by Bosus, a renegade Borg, in an engagement with several rogue Borg later found to be led by Lore. (TNG: "Descent")
Corelki was played by stunt actress Christine Anne Baur who received no credit for her appearance.
According to the script for this episode, the pronunciation for Corelki was "ko-REL-kee".
