Retreat of the Sword Baron

From publisher blurb: A 5th Edition Mini-Dungeon for four to five characters of levels 4-5 The Sword Baron was once a powerful, if immoral, noble and famous duelist. He sought to defy growing old, and through various machinations was transformed into a vampire spawn. Not content with his undead curse, he retained an undead mercenary wizard known as “The Bone Caster”. Recently, the baron summoned a psoglav demon named Kkleva, who extracted the baron’s vulnerability to sunlight, placing it in a statue.
