Ruby Flames — Richard A. Knaak

Delos: a world not unlike our own...until a reckless attempt to capture the primal power of the universe shattered the very laws of nature transforming Delos into realm of magic. Now men vie with monsters, sword with sorcery, good with evil. And behind it all is the dread entity that was reed when the light shattered: the Laria.

Now, thousands of years later, two young would-be heroes--Jarric, a human fire mage and Feryln, a feline mrem warrior--may be the last hope against an unholy alliance of evil creatures bent on the genocide of men and mrem alike!
