|Location:||Pallas 14 system|
|Affiliation:||United Federation of Planets|
Mantilles was an inhabited planet. It was the second planet in the Pallas 14 planetary system. This system was located in the Alpha Quadrant. The planet was affiliated with the United Federation of Planets.
Prior to stardate 5371, a Federation colony was established on this planet. It was the most remote inhabited planet in the Federation, lying at the outer fringe of the galaxy. Mantilles was home to 82 million people, and was governed by retired Starfleet commodore Robert Wesley.
In 2269, Mantilles came under threat by an unknown cosmic cloud creature. Governor Wesley's attitude prevented planet-wide panic, and five thousand children were successfully evacuated before the cloud reached the planet. The crew of the USS Enterprise managed to stop the creature before consuming Mantilles. (TAS: "One of Our Planets Is Missing")
