The Moons of Caina
Rinstoke and its six planets are unremarkable in most respects. Its worlds include a pair of Class 3 desert planets, a Class 4 airless world at the edge of the system, and two small gas giants. The gas giant Caina-the third of Rinstoke’s planets-is an exception. Its vast moon system is one of the largest satellite complements charted to date. Eleven major moons (satellites more than 1,000 kilometers in diameter) and an estimated twenty- nine minor moons orbit Caina.
The moons of Caina are divided into three general regions: the inner moons, the middle moons, and the outer moons. The inner moons are five of Caina’s largest satellites; three of these are sulfur-worlds marked by endless volcanic activity, and two are airless rocks. The middle moons include five major and six minor satellites. Hudson is the first in this group; it’s the largest of Caina’s moons. Its companions are generally composed of light rock and water ice. The outer moons consist of one major and 23 minor satellites. Caina is also surrounded by the remnants of three ring systems. None of these rings is particularly intact or spectacular.
Pirates frequently use the moons of Caina as hiding places and lairs. Rumors of hidden colonies, pirate shipyards, bootleg laboratories, and other unmarked installations abound; these secret bases conceal themselves in the debris and electromagnetic noise of the Caina moon system. Like many Jovian worlds, Caina possesses a rapid rotation and a core of conducting metallic hydrogen-the ingredients of a very powerful magnetic field. Navigation, sensor performance, and communication within the inner moon system are frequently degraded by EM interference. The Baffin Island station on Hudson relies on a series of powerful navigation beacons in high Caina orbit to guide visiting ships to its landing field; other hidden stations simply disguise their beacons as naturally occurring radio noise.
