“Rhombus: Head Paladin of the Brotherhood: Rhombus is the head of the military arm of the Brotherhood, and a teacher of young knights. Gruff, stern, and stoic, he will tolerate no nonsense. He can be a good source of information about people within the Brotherhood.”— Fallout Official Survival Guide p. 101
“Rhombus is the paladin you're searching for when your adventure begins. You'll finally catch up to the old coot in Los, but he's certainly seen better days. Enjoy Rhombus' final hours, mowing down Ghouls together as you make your way to the Vault entrance.”— Fallout: Brotherhood of Steel Official Strategy Guide/Fallout Troublemakers p. 94
Escorting the Paladin: The Initiate follows Rhombus through Los as he makes his way to the truck where he stashed the keycard. The Initiate and Rhombus are ambushed along the way.

"Stuff? I could teach you how to fight...if you had any ability. But the High Elder decreed no training of new recruits until the threat of invasion passes."
"You - you're the only one?!? Those idiots on the Brotherhood council! I warned them that this region contained significant activity! And they sent a - a... You're not even a full paladin, are you? How preposterous!"
"I have fought the mutants all my life, but you may be too young to recall their savagery... They threaten all life because they wish to become the dominant species on earth, crushing the world in their grasp."
Rhombus is a key figure in determining the course of the Brotherhood. The ending outlining his death is described as bringing about a "Steel Plague" that would last one thousand years.[4]
