An Athanor is a special furnace into which a Promethean places Vitriol they have acquired on their Pilgrimage. By placing the Vitriol into an Athanor, they may nurture special Boons that help them as both a Promethean and a human. A Promethean may only choose one Athanor to develop in their lifetime, must have at least three dots of Azoth, and must be trained and instructed by another Promethean familiar with the concept of Athanors.
When a Promethean attains their Great Work and becomes human, the Athanor is the only Promethean power that lingers in their transformed bodies, giving them an advantage they may make use of in their mortal existences.
Athanors are grouped by Lineage, and tend to reflect the qualities that each Lineage values above any other.
Each Athanor is represented by an animal, real or mythical, that the Prometheans think best embodies that trait. Some animals are shared among the Lineages, such as the Dragon, but each Lineage may assign a different trait to that animal.
