Can anyone remember this story and point me to the issue number? It's from the 80s or 90s and is an Annual or other special graphic novel type one-shot. A tween-age witch girl does not age and lives on a boat and she is being stalked by a monster that gets bigger every time it is defeated. She summons Spider-Man into her dimension to be her protector. Her dimension has very little gravity and her pirate ship type boat floats in the air. Peter defeats smaller forms of the monster until it comes back to life as a dragon and Peter uses the rest of his webs to make a fire shield. Ring any bells?
