Dwarf Commoner Origin Edit
The Proving Master is seen in the Dwarf Commoner origin during Proving Loyalties, where a Honor Proving is being held in honor of the Grey Wardens, with Duncan attending as guest of honor. Because Everd passed out drunk in his booth, the Warden donned his armor and impersonated him in the Proving. After winning three matches, the casteless impostor was revealed to the outrage of the Proving Master.
Despite Duncan's attempts to reason with him, he had the Warden and Leske arrested for this stunt, only for them to be retrieved by Jarvia and brought to Beraht's hideout. After the duo killed Beraht during their escape, they were cornered by the Proving Master and several guards. At that moment however, Duncan and Rica appeared, and the Grey Warden formally extended an invitation to his order based on their showing at the arena, much to the Proving Master's annoyance.
Dwarf Noble Origin Edit
When the House Aeducan hosts a proving in it's honour in order to celebrate the first commission of the Dwarf Noble who is the King Endrin's middle son/daughter, there is a different Proving Master overseeing the matches. That probably means that more than one Proving Masters exist.
The Proving Master also oversees the Memorial Proving held in the memory of King Endrin and the Warden may participate in it. During A Lord's Trust: The First Task, the Warden must speak with him to compete in the proving under Lord Harrowmont's name. Note that even if the Warden completes A Prince's Favor: The First Task he/she can still compete in the Proving independently and dedicate the victory to the Grey Wardens or to Prince Bhelen.
