From publisher blurb:
Caravans from the Distant Lands make the slow trek to the City of Skull laden with oddities, valuables, and goods from lands supposedly beyond the Salt Waste. Caravan Guards raised and trained at Skull escort trains of carts and wagons through the long miles of the Salt Waste over tendays and tendays before arriving safely at the City. Those Guards stay alert for Raiders, strange Hazards, malevolent weather, and any number of other perils bound into being within the broken lands under the twilight moons.
But not all such trips end well. What happens to a Guard when their clients are carried off into the true night by winged and buzzing horrors from the sky? What cost will they bear if they fail to rescue their charges from the Hunters of the Endless Night?
Are your adventurers willing to brave the depths of the Salt Waste far from any source of rescue or reinforcement?
