What if the side quest is really the main quest?

Divine, a healer of the Goddess of Souls, has chased the thief who stole her talisman across half of Trelvania. The talisman is the key to accessing her magic well, and without it, she is powerless. While chasing her betrayer, former girlfriend, and servant of the Goddess of Condemnation, Divine meets Saph, a flirty tavern owner with an eyepatch and a proposition. Saph will help Divine locate her talisman if Divine helps her complete a mysterious quest in a chest.
