The Forces of Good and Evil.....
For every force in this world, there is an opposite to it. This is the case for Good and Evil as well, for they have to co-exist and remain at a balance, one side can never truly destroy the other. Sure, one side can temporarily neutralize the other, but it can never truly remove the other side from the world. Thus, the battle of Good and Evil is neverending, with one side occasionally gaining dominance, but never truly winning. Therefore, in the world of Fiction Fantasy, there will definitely still be the forces of Good and Evil. Dragonlance has the Knights of Solamnia and Takhisis, Dragon Prince/Dragon Star has the Sunrunners and sorcerers, while Heralds has the Heralds pitted against the bad guys, mostly blood-path mages and demons.
