The House of Cursed Things

Riath Burgess knows a great deal when he sees one. That's why he purchased the house next to Raincroft Cemetery. Unfortunately, he didn't see the small print.
Cue the adventurers hired by Burgess to go into the house and fulfil the final steps required to seal the deal.
In this horror/mystery adventure for 5e, the characters must play a dreadful game to find and dispel cursed objects. And, like any game created by your unfriendly neighbourhood, necromancer, there are no rules.
This DnD one-shot can be run as a stand-alone game, taking 3/4 hours to complete.
