Pressen

Pressen is a gas giant with a ring system (like Saturn) that has many different moons. The most important moons are the twin earth-sized moons of Jenoa and Arkenos. The planet orbits a sun-like star at a distance similar to earth, but it's orbit is slightly elliptical. This means that during half the year the entire Pressen system gets less sunlight, creating seasons on Jenoa and the other moons. The Pressen year is equivalent to a year on earth.
