It’s been staying within my files for some time because I literally forgot to post it, but here goes -- this is what Waterfall looks like in the universe of my Undertale fanfic, Learn When to Quit! For a number of reasons, most of which being that Undertale’s maps are way too linear for my taste and that I like it when things look more “realistic” (sorta), I wanted to make my own version of what the Underground looks like -- so that there can be one general reference that I can use in order to make sure that the characters do things in a logical way.
NB: The maps are all put one on top of the others, starting with the bottom level and finishing with what the Surface looks like. Areas with transparency mean that it’s literally a hole and that people could peak their head through it in order to get a glimpse of the level below. The only thing that prevent monsters from reaching the surface through that hole is the Barrier, which is still effective at that location. However, the holes are responsible for the rain and sunlight that can come down in certain parts of the Underground, notably the statue hiding the music box.
I also have a map of Snowdin in the works, which notably includes the “boat rent” from chapter 10! It’s mostly usable for its landscape and general geography parts, but I have yet to fully determine the layout of the main town (where the shops are, whether there are sites that the Players can’t normally access like a school or a sparring battlefield for the Canine Unit to train, stuff like that). It’ll probably come out one day when I bother to finish it :x
