History and specifics
In the 2270s, Parides IV was non-aligned, but strategically relevant to the Federation.
In 2276, Paridesian officials chose to open diplomatic relations with the Federation. The starship USS Enterprise was sent to Parides IV, bringing ambassador Alec Raymond. An urgent mission came up along the way, however, so Raymond, James T. Kirk, Spock, and Leonard McCoy ended up traveling there aboard the shuttlecraft Hoyle. The Enterprise later entered orbit to pick them up. (TOS - Untold Voyages comic: "Silent Cries")
