Aventuremode experimental mode made seed.

This world was made to be a hellworld (for adventurers and forts alike!)

We have Mirthful areas with volcanoes and haunted beaches. Half a continent is sinister. All races still exist.
There are multiple volcanoes in an evil lake. More or less wherever you find good, you will have evil right next to it. Savagery is high.

World gen changes (not all but the important ones).
1. More Volcanoes
2. More Warebeast types
3. More Vampire types (like... Be very vigilant)
4. 169 Megabeasts
5. 13 Titans

And most of the bad/evil stuff have had their numbers buffed somewhat in worldgen.
