The Folio #17

From publisher blurb: With the docks of Distant Turtle City behind them, the challenge of the city's castle still lies ahead. Ancient dwarven samurai were lords of the mighty estate, but now it has fallen to darkness. What secrets and horrors might be found there are disheartening enough, but with a city of the shadow dead at their backs, the adventurers have little choice but to put an end to Molo's corruptions once and for all. Come join the battle against legendary tortoise oni, stealthy gaint mantises, corrupted beasts, undead half-dwarven guards, and even a rumored shadow dragon! WS4, Samurai's Fall, is an adventure module in 1E & 5E formats for characters levels 6-9
