Time to stop being a lurker and give a little something back to the community. I don't think this would be considered Dwarf Heaven, but I thought people would enjoy it.
A 6x6 site that has:
Magma Pipe
Underground River
Underground Pool
Chasm across the entire length
HFS
Limestone (Plenty of It on the outer ring)
Layers of Obsidian in the middle
Sand
Optional Bottomless Pit
Plenty of Savagery
Unfortunately it's temperate so no Elephants or Hippos or regular river
But I hope you enjoy it. Thank you Toady for this happy game. Oh and I made this using Mayday's tile set.
If you search for UR, HFS, Magma Pipe and Flux it'll pop up with site finder.
Here's the other settings for Gen. And yes I put 150 Volcanoes.
