We’re all privy to the dark secret of Trollskull Manor—and soon your adventurers will be too. Alas, Waterdeep: Dragon Heist comes up short on providing an adequate haunting—it merely informs you of the presence of the poltergeist, and provides two brief descriptions of what can be done with him. That's it. No antics provided, no scenes.
The Haunting at Trollskull Manor is a short adventure balanced for four 2nd-3rd level characters for chapter 2 of Waterdeep: Dragon Heist, and is designed to be completed in two sessions as the adventurers confront the ambulant spirit(s) that haunt the manor. It expands upon the grisly history of Trollskull, particularly the dark chapter it spent as an orphanage headed by a cannibalistic hag.
Spanning three acts, the first involves Lif the poltergeist's violent antics, leading to his eventual confrontation. Act II begins days or weeks later—just long enough for the adventurers to feel safe in their new home—when the ambulant dead return, heralded by several paranormal occurrences. The final act involves the return of the Hag-Shadow—a sliver of the hag's evil—as it seeks out to devour the last three ghostly survivors of her murderous past.
This adventure can be replicated in any campaign, for it bears few spoilers to Dragon Heist. Use it whenever you need a tavern or manor with a darkened past and tear away your players' safety blanket!
