The ancient City Builder ruler who reigned from the dream-castle called Heaven. A statue of the ruler once stood on a pedestal in the city below, Zrillir City. According to legends of the Hairy Ones, as related to Louis Wu during the First Ringworld Expedition in 2851: Zrillar ruled for many lifetimes, throwing sunfire from Heaven when displeased. The lands below provided Heaven with many types of food. But there came a day when it was suspected Zrillir could no longer command sunfire, so the people rebelled and pulled down his statue. Later they tried to invade Heaven, but Zrillir caused the stairway to fall. Then his angels left Heaven in their flying cars.
