A thirty-second-century species whose refugees were dying of a prion disease at Federation Headquarters until Discovery recovered the plant samples needed to cure them.
The Kili are a humanoid species of the late thirty-second century. They are met in the Discovery episode Die Trying, in which the ship arrives at the hidden Federation Headquarters and finds a group of Kili refugees in the infirmary, gravely ill and close to death.
Starfleet's doctors trace the sickness to prions picked up when the travellers stopped at the planet Urna and ate contaminated food. A treatment can be made only from an uncorrupted sample of the plant concerned, and the nearest is aboard the seed vault ship USS Tikhov.
Admiral Vance, wary of the newcomers from the past, allows Discovery to jump to the Tikhov with the spore drive. Burnham, Culber and Nhan retrieve the seeds, the Kili recover, and the mission earns the crew its first measure of trust.
