You decided to deliver the remedy to Vili. He confessed that he had feelings for Sinigalla too, and asked you to break her curse in his stead. You went to Silentera Canyon and freed Sinigalla. You told her what Vili had done and why. She decided to follow her heart and be with him. At her request, you delivered a message to Nep, who was heartbroken, but glad that she was free of her curse.
