New Appalachia Bank
Regarding the extensive damage to the bank's superstructure, the explosion from the botched robbery of Armored Train 781 has completely crippled the building rendering it uninhabitable. We're saddened by the loss of life that occurred, and donations have been made to the appropriate families. For temporary job assignments while we access repairs, please contact bank administration immediately.
