For years dwarves have continuously dominated the worlds. Time and time again dwarves have risen to victory through all the challenges thrown at them. The dragons have been tamed, the giants slaughtered, the titans destroyed, the ettins decapitated, and the Clowns have been encased in obsidian. Goblins have been slaughtered by the thousands, elves have been snapped in half like twigs, kobolds have been stomped mercilessly, and the humans have been pillaged for all they're worth. Regardless of how hopeless, crazy, disheartening, disturbing or bazaar the lives of dwarves have been, they always seem to pull through (often using magma).
Not anymore.

Rise of the False Gods (RFG) is an intensifying mod that will at some point become a total conversion. For now it will simply be an expansion on vanilla.

The concept behind this mod is the image of a new found world where the mortal races cower in the nooks and crannies of the world while terrifying primal beasts stalk the realms. The mortals, in an attempt to save their short lives align themselves with these beasts and worship them as False Gods.
The game will kill a lot more dwarves, have a lot more danger, have a couple of surprises, and fight you at every turn.

The mod is characterized by a higher probability (not a guarantee) that mortals will worship megabeasts. It happens in every run that I've gone through in testing as long as there are sufficient megabeasts (15+ is good, but if you go to 100+ they start killing each other in battles of epic proportions).
