G715
From Tardis Wiki, the free Doctor Who reference
G715 was a toll port that helped to raise money for the Confederation. One of its walls depicted a mural featuring all sorts of creatures that had used the toll, including Solterns, Giboks, and Wormese; the paint was barely two thousand years old. (PROSE: Delta and the Bannermen)
In the year 4687, (PROSE: TARDIS Cam) the Seventh Doctor and Melanie Bush landed at G715, becoming the ten billionth customers and receiving a free trip with Nostalgia Tours. The Chimeron queen, Delta, landed at the port and joined the tour bus before it took off, being pursued by the Bannermen. They killed the tollmaster before leaving, since he wouldn't reveal where the bus was headed. (TV: Delta and the Bannermen)
