Near the Romulan Neutral Zone
Calder II was the second planet in the Calder planetary system. This planet was located in the same sector as Barradas III, Yadalla Prime, and Draken IV. This sector was located near the Romulan Neutral Zone. This planet was the location of ancient Sakethan burial mounds, a site that was associated with ancient Debrune artifacts.
By 2370, Calder II was the location of a small Federation science station and outpost with limited defensive capabilities. The outpost and the ruins were protected by a type-four deflector shield and the station was defended by a minimum of two phaser banks.
