The Phthonus Cabinet – A Gaslight-era Scenario for Call of Cthulhu

Banner: The best cosmic horror & Cthulhu Mythos @


Jonathan Adley has a problem. Last week, he couldn’t believe his luck when his Auction House in east London broke profit records, largely thanks to an unusually fierce bidding war over an 18th-century ebony cabinet. Yet soon after, Adley was dismayed to find several items delivered to the wrong address, and now the prized cabinet is missing! Worse yet, the winning bidder threatens to sue him into insolvency if he does not produce it within a handful of days. Yet financial ruin may be the least of anyone’s worries, as everyone gets more than they bargained for with The Phthonus Cabinet.
