This is book number 9 in the Runelords series.
The great war with the Wyrmling Hordes is over, and mankind has lost. Lord Despair has gathered an army of fell creatures, planning to unleash them like a wildfire across the stars.
Those who oppose him know that the battle is all but lost. Though they stand against the darkness, they cannot hope to win with arms. Indeed, they stand against him armed with little more than principles.
Fallion and Tuul Ra, with only a handful of allies, must hope that with resolve and cunning alone they can win the day--before darkness closes upon them forever.
