An Enemy Reborn - Stackpole Michael A.

In Chaos, a new power arises, an evil more ancient and more awesome than Fialchar himself, the one who broke the Seal of Reality and let the Wildness spill over the world.

Locke became a Chaos Rider to find his lost father, and now Locke must become the very hero that he himself has been seeking. The only hope of defeating this new Darkness is with an unlikely alliance of Empire and Chaos forces, led by an untried swordsman from beyond time.
