Alina Gray, a magnificent artist who explored life and death, was previously the main antagonist of AST 1. After tricking the party into believing she was an ally, allll the way to absorbing enough negative energy to destroy the whole city, she's had a rough ride. However, when confronted with the decision to kill her or let her live, Hal and Cole (AST 1 protags) decided to spare her life. When she awakes, she finds herself in a hospital bed, only...she has no recollection of who she previously was, and whenever she tries to remember something, she draws a blank. What could've caused this...?
