During the time of the Cold War between the Galactic Republic and the Sith Empire, the Bank of Aargau began emptying out all safety deposit boxes in the bank that had lain unclaimed for more than four hundred years. Walon Vau had an account in the Bank of Aargau where he invested both his mercenary earnings and his Cuy'val Dar fee. In 40 ABY the bank had a branch on Coruscant where Boba Fett had an account.
