在Roger Maxson死后,他的儿子长大了, Rhombus assumed the mantle of Head Paladin. After the death of the Master, the Brotherhood of Steel moved to aid in the eradication of what was left of his army; however, a Super Mutant faction under the leadership of Attis had plans to start anew with a hidden Vault in Texas. Rhombus, despite some criticism from the other elder council back in California, begins operations against the new Super Mutant army, now led by Attis. They traveled to the East to Texas. Here, he discovered the abandoned Vault Prototype and established a new base of operations within. Their heraldry was altered, showing a pair of crossed pistols instead of the usual sword and reflecting their new mission: the eradication of all Super Mutants.
