The Primarch (pron. Pr-eye-mark) of the Church is the spiritual and political leader of the Reign. The position is generally held by an older man, having risen through the ranks of the various sub-Marchs to his position. The Primarch resides in the holy city of Volant, seat of the Church's power.
Matthias III
The current Primarch, Matthias III (b. 2745) began his tenure in 2791, after the death of his predecessor, Julian XVI. Matthias III was at the bedside of the dying Primarch, and allegedly collapsed into a coma before the physician had even formally declared Julian XVI's death.
Matthias was born Rikkan of Doenmarach, and is the first Primarch known to be of Wildborn heritage (his maternal grandfather was a Druid, killed during the Wildborn Wars).
Spiritual Role
As leader of the Church, the Primarch has a direct and personal connection with Likos. His word is considered canon, and there are no religious restrictions on his authority.
The Primarch also has a vague telepathic link with every sub-March. At lower levels, this manifests as a sort of conscience, vaguely directing the Tetrarchs towards whatever end the Primarch dictates.
