The Ethereal Spire
In the center of the palace of Araniae, a huge tower rises over the city. At its peak hovers an immense crystal filled to the brim with magical energy and humming with power. Three concentric mithril rings rotate the gem to help channel the energy down into the tower and the city. The crystal's light can be seen for leagues around the city, and its constant glow is a site the citizens of Araniae have long been accustomed to.
Created by, the Etherealactrium is the primary source of Etherea's power. It draws magical energy from the land itself, which is then directed into the city through the Spire, which stands below it. Hundreds of smaller crystals in the tower house enchantments that help control and direct the artifact's power. This power is primarily used for running and maintaining city infrastructure and services, and private citizens can purchase power from the kingdom for personal use if they wish. The artifact is monitored by specialized conjurers called Etherealists, who communicate any issues immediately to Etherea's High Sorceress.
