Chaos ruins are areas infused with entropic energies. In the Cinazan Front, three of the largest places to suffer this fate were the cities Hareldocáno, Erchinor, and Sakarumân. Buildings and homes were shifted and contorted, yet do not fall, others became clouds of floating debris, buoyed by newly created earth motes, or submerged in water motes. The fires of war, particularly the funeral pyres, became the heart of fire motes. The wind and climate of a chaos ruin is often different than the land beyond its borders. The Winds of Hareldocáno, powered by air motes always blow in haphazard patterns. When they go against the natural winds, so come great eddies, tornadoes, and dangerous storms. The ice fields of Sakarumân, frozen to a depth of three miles, are one of the more unusual weather anomalies that can come out of being made a chaos ruin.
The First Horde of Chaos is blamed for turning Hareldocáno, Erchinor, and Sakarumân into chaos ruins.
