The Horseshoe Calamity (5E)

From publisher blurb: Cold as Winter's Heart On the frozen frontier far from civilization, a recently-disturbed shrine to an evil god has brought chaos and conflict to a community of centaurs and humans. The humans blame the centaurs’ greed for the plague of undead, and the centaurs seek a powerful magic item—starting with a single horseshoe—to put the threat to rest. Will the spirit of chaos bring all-out war or can both sides face down an ancient menace that threatens to destroy them all? The Horseshoe Calamity is a wintry wilderness romp for four 7th-level characters using the 5th Edition of the world's most famous RPG.
