Caravan of Peril takes place on the unprotected roads and trails of the wilderness between cities.
Merchants, pilgrims, and wanderers have long banded together in wagon caravans for safety when setting off into the wild -- yet a caravan is only as safe as its hired guards. There's plenty of coin to be had on the road for those with a swords (or spell book), a steady will, and a taste for adventure.
This adventure begins assuming the characters have all signed on as caravan guards. Their motivation may be money, wanderlust, or a hasty need to get out of town. Whatever the case, payment is 25gp each, paid upon safe arrival in the next city.
Along the way, the characters will brave the dangers of the wilds, make some unusual acquaintances, and be ambushed by crafty goblins.
