Once a fortress where wizards honed their eldritch craft, the Scarlet Citadel now holds a sinister reputation—and for good reason. The dungeon’s well-trod stairs have seen few return from their journeys below. Now, malevolent creatures spin shadowy webs, enchant foul magics, and summon forth dark gods. But for those brave enough, ancient treasures and secrets still lie scattered everywhere. Inside the Scarlet Citadel, you’ll find: • A classic-style adventure for 10 levels of play, fully compatible with the 5th Edition of the world’s oldest roleplaying game. • Evocative combats and magical mysteries brimming with plots and subplots. • Tons of original traps and new monsters, as well as a complete write-up of the nearby town of Redtower, where the adventurers can set up a home base. • An adventure easily paired with the Scarlet Citadel Map Folio, a fold-out set of playable battle maps from Kobold Press. • Plus much more!
