The Paladin Berrorgar was named Barron of Cromm's Hold by the Ducchess of Daggerford in fall of the Year of the Star Walkers Return after he liberated the keep from the control of the Blackguard, Baroness Wynne Cromm.
The former baroness had been discovered working with a Succubus named Pencheska. Pencheska had been masquerading for some time as the Ducchess of Daggerford, while the true Ducchess was a prisoner in Wynne Cromm's dungeon.
Berrorgar hails from Cormyr where after his rebirth as a dragonborn, he was tasked from a vision gifted by the high priest of his order to travel to the sword coast. His task is to stop any influence Tiamat may have over the area.
