Sky-Stone-River-Place (d20)
Here is Sky-Stone-River-Place¸ an experimental dungeeon I did a while ago.
This was originally concived and written around the time of Veins of the Earth and Deep Carbon Observatory so it has a lot of the same concepts/monsters etc. In a way you can think of it as a little brother to DCO¸ or a twin that got absorbed in the womb and became a vestigal twin that gawps beneath a concealing top hat.
This is pretty short¸ about 5000 words. It does have bookmarks and hyperlinks but in every other way its pretty bare bones. There is a diagramattical map¸ no art and it HAS NOT BEEN PLAYTESTED IN ANY WAY.
So quite literally¸ pay what you want.
