City of Light

 was created to a location where a meteor fell during the last planetary alignment some 3600 years ago, from that meteor they also forged the Triangle of Light. The People of the Light worshiped the Triangle of Light for it's power to control time. Abuse of that power lead to the destruction of the City of light. The few survivors split the Triangle and hid in the opposite ends of the world, to ensure it's never used again.
