In this adventure players are set first on a simple task, to solve the disappearance of the local witch before outside forces take an interest. But as the players get deeper, they will rapidly kind themselves on a quest for far more, as they range from an alchemist's lair on a crumbling tower down to a dark swamp full of mystery and danger, seeking a holy relic that might lead them to the outskirts of Hell itself. All in service of the sleepy Village Sujeira and the dusty souls within. 1452: Saving Sujeira’s Soul is an adventure set in northern Portugal on an alternate history Earth during the year 1452, in a world where history is much the same, but for the fact that the Rus are all hirsute dwarves, the hordes that poured out of central Asia were orcish (and half-orcs are mostly janissaries split among the Ottoman Empire’s demesnes), and elves are creatures of rumors and myth. Halflings live among the English and Portuguese in villages and farms, while goblins are pests best left for dead in the wilds between civilized countries. The Church arms its inquisitors with holy blessings, for witches are not mere milk-souring old women but vile devil-pacted souls, and wizards and sorcerers seek human and kine for sacrifices to fuel their darkling magics. There be dragons on the edges of the world, and ogres and sea serpents and giants, but the alchemists of this world know things beyond mortal ken and fight these horrors with science and canny concoctions.
