Info:

Located underground, This Beautiful place has many waterfalls, and is Based on Waterfall from Undertale. It is mainly cut off from Calistan, the Only Entrance Being by the Mountain range north of Calistan in a gigantic Ravine. The Pink Lake is located inside, and allows safe entry, via jumping down into it’s waters, from the edge of the Ravine. It is a 100ft drop, so be prepared. The Village of the Pink Lake Also surrounds the Pink Lake on All sides, including on the side the Ravine meets with. This part of the Village is called Darkstead, and is Inside of the Ravine. It seems to climb the Ravine wall it is under,and is mostly dark. Darkstead is Kept separate from the Rest of the Village, separated by the Pink Lake. This Area shall be my undertale based Characters playground. And is where all Undertale based characters, that aren’t in different Realities, and aren’t the protectors and co, exist. This Includes T.M.M. Labs. Also living in it is Cynthia and the Locket Beings. There are actually several entrances, and the entire cave system is known as The Underground. Darkstead is a more Deltarune based location. Day, Elizabeth, And Cynthia are all fallen children, who fell into the Underground. And all of them met bad fates, in that they all became melted monsters. This place is full of beauty, and hidden horror if one knows where to look for it. Most of the transportation involves boats, due to Rivers connecting most locations. The Entire Ravine is called Paradise Ravine.

It serves as the entrance to the Underground.
