The Beacon of Souls is a sacred lantern given to Zeke Holloway by Madame Leota. A source of light and power, this ancient artifact can harness the energy of souls and is powered by six Soul Gems. Zeke uses it to combat the dark forces of Atticus Thorn.
The Beacon was created by the members of the Brotherhood of the Soul. Its purpose was to ensnare and purify evil spirits for guidance to the Afterlife. However, if the Beacon were to fall into the wrong hands, it could cause harm to the good spirits and cast them into the fiery Afterdeath. The Brotherhood vowed to protect the Beacon - as well as the balance of the Spirit Realms - from Thorn and the followers of the Order of Shadows.
In secret, the Beacon was passed down throughout Europe, just out of Thorn's grasp. But as time went on, the followers of the Brotherhood perished, one by one. During this time, Thorn took steps to replenish his cult and continue the attempt to find the Beacon's whereabouts. The Beacon eventually found its way to the New World, in the bayous of Louisiana.
