Hey, Eric.
Thanks for taking the time to comment on the book. I understand that you’re trying to have the player explore outside and beyond the dungeon walls.
In Val’s Revenge, the player is permitted only to travel within the dungeon walls, which means travel elsewhere is not possible or expected.
You can, of course, change the design, and use what you’ve learned in the book to set up other scenarios where that type of travel path is allowed. Hope that helps!
