This is a Dungeon Crawl Classics adventure set in Lankhmar for level 2 characters by Goodman Games.
From the Publisher:
Follow those hands! Rooga the Fence has a weakness for the strange and bizarre. When a curious pair of silver-plated skeletal hands animates and escape the shop, where will they lead? Legend claims they will reveal the way to buried treasure. Will the PCs follow?
Following the twisted path, adventurers encounter once-slumbering magic now called back from beyond the grave. Someone, or something, wants them to explore the vaults beneath Lankhmar’s streets. The Fence’s folly is fortuitous…but fortuitous for whom?
