The Haunting of Manor Thessalia

By: John K. Webb

Explore the Haunted Mansion and confront the Vampire, Lady Thessalia!

The Haunting of Manor Thessalia is a Fifth Edition adventure designed for three to five 7th- to 9th-level characters and is optimized for four characters with an average party level (APL) of 8. The characters are invited to investigate a mysterious haunted mansion in the swamp, where they discover a vampire’s private “blood bank.”


Countess Thessalia was once a young noblewoman who was willingly turned by Count Caedmon, her husband, over a century ago. After the Count was slain by a vampire hunter, Thessalia took over the estate and retreated far from the public eye.

In order to satiate her appetite for blood, Countess Thessalia keeps a personal “blood bank” beneath the manor; those unfortunate enough to be imprisoned are often kept alive for as long as a year. Thessalia chooses her victims carefully, preferring those who’ve slipped through the cracks of society. Recently, a young human male called Aeson fell into her clutches, and his father has begun asking questions around town.

To dissuade would-be investigators from entering her estate, The Grand Hostess has purposefully transformed her mansion into a haunted site. Those who lay eyes on the mansion often report strange lights, floating orbs, wailing voices, and ghostly figures.
