Brian Highcastle was the Baron of Highcastle during the Riftwar up until the Great Uprising. A southern noble, he was often criticised for not understanding northern warfare.
During the Riftwar, Lord Highcastle came to help Roald's army who was holding off goblins from the Cutter's Gap. 
He received the company of Arutha conDoin and Guy du Bas-Tyra after the blowing up of Armengar. Brian did not believe their word about the army of moredhel and goblins and soon the fortress was overrun by Murmandamus' army where Brian lost his life. 
Afterwards, King Lyam named Baldwin de la Troville to succeed to the position.
