The Riddles of Ridayah

Three forest fire combatants are mysteriously awakened in a strange land. Though separated, they meet and befriend many of four distinctly different species who have been invaded by creatures from beyond a barrier wall. While aiding their friends, they discover this land is on a world constructed about a small black hole by those who may pose a serious threat to their own. With too many problems and too little time, they must race to solve a millennia old riddle.
