Restored from a backup.
Backup made by Unknown Party (not necessarily by Aria, or with her knowledge), for Unknown Reasons, at an Unspecified Point in Time.
Also, memory editing. A capsuleer brain scan can be held as data, and examined by psychologists (reference to this in the amarr epic arc missions). If it can be held as data, then flip a few 0's to 1's and so forth.
Ta-da. Use all your skillpoints, with a PF-accurate mode of resurrection, and an initial Quest - find the identity of the Unknown Party and their Reasons.
