Celes II was the inhabited second planet orbiting the primary Celes, in the Beta Quadrant. In 2379, the praetor of the Romulan Star Empire called for a vote on a motion to open trade negotiations with this world. The motion to open negotiations was brought in response to the fact that the dilithium mines on Remus had not been filling their quotas for a matter of months. (Star Trek Nemesis; DIS: "Magic to Make the Sanest Man Go Mad") Celes, the primary of Celes II, was located in the Beta Quadrant on a star chart seen in the Star Trek: Discovery episode "Magic to Make the Sanest Man Go Mad" .
