Random Events
Random Events were introduced with the Stellar Phenomena DLC for Sins of a Solar Empire: Rebellion, they are a series of randomly generated events that effect the outcome of planets.
Coronal Mass Ejection
Generates at the system's star (except for black holes) and moves randomly between gravity wells for a period of time. Disables construction and weapons in affected areas for a period of time.
A highly energetic wave of particles ejected from the system's star. Weapons are disabled by the CME and planets affected must delay construction production until it passes.
Gamma Ray Burst
Appears randomly outside the star system and moves between gravity wells for a period of time. Damages shields and gives all weapons a chance to bypass shields; also kills a large amount of an inhabited planet's population and limits population growth for a period of time.
Partisans
May take place on any planet flipped by enemy Culture. Spawns a fleet of Rebel controlled ships of the previous owners race at the flipped planet who will attack anyone who comes near.
Plasma Storm
