Entropy

I tried out the Warhammer fantasy role-playing game system as a teen when it was new, and even read a couple of the novels set in its world. One of the things that stood out to me as strange was that the struggle wasn't staged as a fight between Good and Evil, but between Order and Chaos. As the Wikipedia page says: "One of the most identifiable features of the Warhammer setting is Chaos. While the forces of Chaos in Warhammer Fantasy Battle are depicted primarily in the form of marauding dark knights and beastmen, Chaos in Warhammer Fantasy Roleplay is an insidious force gnawing at the fabric of society." And your heroic characters might hold off the forces of Chaos for a time, but ultimately the world is doomed and those forces will consume everything.

At the time I thought this was an odd and hopeless way of framing the world. Now, as a parent with two little ones, I completely understand.
