After seeing the final cut scene involving Mellori and Grandmother Raven agreeing to end to spiral, it made me imagine ideas for what to happen next. my major idea is the final battle while we know the final battle will most likely be in a dungeon like any other. however i personally believe grandmother raven will not only defeat spider while were fighting in the dungeon. i believe we will have to end up fighting her for the spirals safety. one thing thats points to this is because grandmother raven created the spiral. which gives her the right to end it. however spiders chaos and shadow could merge with her to make her go completely insane. which would lead you to fighting grandmother raven so you dont die along with the entire spiral.
