Beacons are great towers full of mystical energy. Great and skilled Arcanists can take advantage of them to fuel feats of magic.
After the ancient war between the Precursors and the Architects was over, the Architects left the world of Evenor in the hands of humanity, after having granted them powerful towers of supercharged energy called Beacons. Beacons could be used as an energy source for skilled Arcanists. These Beacons are so powerful, major cities and civilizations were built around them, including the Avar Throne of the Avar Imperium and the Citadel of the Seven Winds located in the Dominion of the Seven Winds.
