The Flooded Reliquary
Recommended Levels for Basic Fantasy
Levels 1 to 3
Location: A half-buried stone reliquary cut into a low hillside near an old trade road. Locals avoid it after dark.
Theme: Neglect, damp stone, forgotten worship.
Tone: Quiet, uneasy, with sudden violence.
Background: This place was once a minor shrine and storage vault used by a rural cult devoted to a river spirit. When the nearby stream shifted its course decades ago, parts of the reliquary flooded. The caretakers left. Creatures moved in. Some relics remain, warped by damp and time, but still valuable to the desperate or the foolish.
Adventure Hooks
• A farmer’s son vanished after sheltering near the hill during a storm.
• A traveling priest offers silver for proof the old shrine has been cleansed.
• Goblins have been spotted carrying strange coins stamped with river symbols.
• A drought has locals believing something below the hill has been angered.
