Kalraka Dzeik is a sentient lightning storm with a following of cultists. It has much in common with a natural disaster or a plague; it starts at a single point but spreads like wildfire if given the chance. It is capable of terrible destruction, and will take heroic effort to stop, if it can be stopped at all.
The Omen Star: In the West, in what appears to be an eccentric orbit, appears the Omen Star. The appearance of the Omen Star in the first house of the sky bodes "great things" for good or ill are about to happen. It is the rest of the stars that determine if it is for good and ill. Thus people are always looking for things to happen during the time of the Omen Star.
