Tastiella was originally a high priestess of Em Pheyna during the Second Era. According to Shurelia, she sacrificed herself in order to seal Mir. She now acts as the Crescent Chronicle's terminal to oversee the physical world and therefore can only move within Em Pheyna and the Crescent Chronicle proper. Her "body" is severely damaged later in the game, but she manages to oversee the end of Lyner's journey and congratulate him, before bidding farewell and disappearing, thus dying as she wished.
