Prophetess
In Dantic
The Prophetess is historically either the titular or empowered ruler of Ironesse and the spiritual leader of the Church of the [Eternal Way]]. Her bloodline is supposedly unbroken back to Deus Irae, who is worshipped as a goddess in some areas of the Blaenau Gwent continent. In reality the bloodline has been broken several times and passed on spiritually to a chosen surrogate daughter.
This is the case in present-day Ironesse, where in absence of her daughter, Kalinthen Fait was forced to choose a new heir in Naru Hitome Xu. Most Prophetesses are very strong psionics, though all at least have a weak precognitive ability. When a natural heir isn't available, a likely girl of very strong psionic ability is always chosen.
In Esper
Many thousands of years ago there was a sect of Wayists that split from the Ironesse Church. They believed their Prophetess, Tesorio was the true line of Dues Irae, while the Wayists reviled them as heretics and drove them first from Ironesse and then from Dantic completely. Eventually they found their way, via the Sills to Esper (dimension) and settled on the uninhabited Triangle Island. There they built great cities and interacted with the native Esperians during the age of the espers, though as the War of the Magi neared its cataclysmic end, their Prophetess, driven by a powerful vision, sent the entire civilization underground.
In Triangle society, the Prophetess serves much the same role as in Ironesse, though she rules with the aid of a Council of Holdings and a First Speaker of the Groundlings who himself has no Holding.
