Duane Rowanmantle, heir of House Rowanmantle
Played by EdinSumar
A group of adventurers uncovering by mere chance a outbreak of living shadows in the Tilverscar were quite surprised when they ran into the young Heir to the Rowanmantle family, Duane Rowanmantle. Claiming that he was there to set things right and fulfil the long-forgotten obligations of his family to Tilverton and the Moonsea Ride, the young Rowanmantle soon found his way to Arabel - intent on staying there for the foreseeable future.
Only time can tell what will come of this, and whether others shall follow him.
Updated to indicate the DM vastly prefers Official Clergy to be 'earned in game.'
Obviously, certain faiths such as Siamorphe, who values the status of one's birth over the actual talent of the character, have reasons to apply on creation. However, titled clergy is earned in game, more or less.
There may be other situations where you're character say- converted to Cyric while remaining in the church of Shar or Bane and uses their resources to fuck over said Faith…
