History and specifics
By 2267, Ramedes III was a dying planet.
In 2267, the USS Copernicus rendezvoused with the USS Enterprise while orbiting Ramedes III to take aboard Rell, a refugee from Theta VII who was a worldsinger able to telepathically absorb and share a planet's cultural heritage. Rell then visited the surface of Ramedes III to record its essence for future generations. (TOS comic: "Worldsinger")
