No, this mod still has elves - so maybe it isn't actually dwarven paradise.

This mod replaces the entire world with:
* Obsidian for all rock layers (and it's now a flux)
* Black sand for all soil layers
* Tower-caps for all trees (indoors + out).
* Non-metal rock veins don't exist.

Other non-tree vegetation (crops, shrubs, etc) has not been modified.

You'll need to generate a new world for the mod to work obviously.

All metals and gems should still be present, but they may be far more abundant than they should be (because they're all present in obsidian layers). Non-metal veins have been removed. Gem balance is also probably somewhat crazy for similar reasons.

If you don't like aquifers, remove the [AQUIFER] tag from matgloss_stone_soil.txt. Makes for fun oceanside forts.

Feel free to use this as a base for other similar mods, no credit required. It is unlikely that I'll be updating this mod.
