Draven's bank

Draven has an account with one of Bankton's many banks, which he used to store his spare eldritch eye before teleporting from Laric to Vistria. When he did so, the bank used a psionic power to store the psychic equivalent of biometric data as a way of securing his account.
GE-7 later deposited the worker construct containing the remains of Ginaron Controller at the same bank, with instructions to turn it over only to Draven, not even to him, in case he was taken over by a Dark Ancient. This, as well as a letter hinting at the existent of a second facility to the north, would have been an excellent plot hook if the party had investigated significantly earlier.
