Bryce Garrahan was the operations manager for the Garrahan Mining Company. A level-headed, pragmatic man, loyal to his mother to a fault, Bryce tried to do his best and keeping his company afloat in the face of the unrest caused by AMS and Hornwright Industrial Mining Company, their primary competitors. The beleaguered Garrahan was in deep financial trouble due to the expense of the Excavator power armor project and decrease in mine output caused by walkouts and riots, coming to a head during the riots. However, despite the vandalism and damage caused by the rioters, including the Bramwell bombing that took down a Mega Mansion, Bryce firmly believed in giving miners a chance and continued negotiations even during the riots. He stood by his mother's peaceful convictions, even in the face of easy solutions... Or his brother, Bill's interference when he took his Strike Breaker minigun to shoot up protesters at The Rockhound.
Bryce was also notable for another reason: He was secretly in love with Penelope Hornwright, heir to the Hornwright empire and COO of the company. The two have known each other since children and friendship bloomed into affection that could have peacefully merged the companies, were it not for their parents' Shakespearean pigheadedness (and the Great War).
Bryce Garrahan is only mentioned in Fallout 76.
