If you go to https://dashingdon.com/play/Sashira/monsters-of-new-haven-high/mygame/scenes/startup.txt you will see the first file, which is mostly a list of variables. At the bottom of that page is a list of scenes. Replace “startup” in the above link with the name of any of those scenes (remember to include .txt after the scene name) and you will get the link to that scene. For example, https://dashingdon.com/play/Sashira/monsters-of-new-haven-high/mygame/scenes/character_creation.txt
