Three caravans have vanished traversing the Cowcheanne Way. The legendary Tahsis platoon, warriors thought by most to be invincible, are dispatched to investigate and are never heard from again. Rumours of native uprisings and bandit armies grow wilder and more widespread every day, while the more devout whisper about the return of the Horde, a mythic foe from ages past.

The truce between the warring Kael-tii and Ashai nations is put to the test when a new caravan is outfitted and they are forced to travel The Way together. As an ancient evil is unleashed upon them, a group of heroes, friend and foe alike, must band together for survival.

When the true nature of their mission slowly comes to light, the growing distrust between the Kael-tii and Ashai camps threatens to tear the caravan apart. Can they set aside their differences in time to combat the menace that imperils them all, or are they doomed to join the ranks of lost souls claimed by the cursed Cowcheanne Way?
