The Lost Water Clock of Thoth

From publisher blurb: Every Lots of Horror offering provides an item lot presented as though part of an auction. This is an easy way to introduce the item into your game: someone bought the item and now all hell is breaking loose! This release includes the The Lost Water Clock of Thoth. Discovered during an archaeological dig far from Egypt, most believe this "ancient" water clock to be a clever fabrication. Since its discovery, this device has not failed to keep impeccable time, but it is said that those who stare too long into its passing waters fall victim to flashes of what may be.
