Candelar IV is a Federation member world. The USS Pegasus picked up the war criminal Endyk Plure from there in 2357. Plure had commited multiple atrocities in the Candelar system, and the Candelar authorities asked the Federation to take him off-planet so the mobs on Candelar IV didn't kill him before he could be put to trial.
