About
I just threw this together for fun. The heights are mostly based on my intuition. I hope you enjoy it! I've added some lorebook settings, but I'm not sure if they'll work perfectly... I'll be tweaking things here and there, so please bear with me if things get a bit weird. Feel free to be a random passerby who forces everyone to eat 'Become a Gnome' mushrooms.
