The Beacon of Alent was a name given to a pillar of pure magic which shot into the sky from the remains of the destroyed reactor core of Alent. The pillar came out of the throne room of Etemenanki, the city's central ziggurat, and was visible to travellers far from the city. The Beacon had been active since the Reactor Core Explosion which leveled Alent's predecessor Lutherin during the Great War. The Beacon went unstable at the end of the Battle of Alent and caused the Catastrophe which destroyed Alent, created the Anomaly and rearranged the continents as it ushered in the Fourth Age.
