The vault was sealed eons ago, and the Titans are believed to have retreated into its depths to one day emerge to create a new beginning after the Oldest War. Deepvault has now been opened, and the power of the long-dead Titans has been unleashed. Deepvault: Machinations of the Ancients is a thick slab of gonzo fantasy, marinated in magitech sci-fi, and grilled over a smoldering bed of Tabletop Terrors charcoal. It's a little weird, a little mad, and a whole lot of awesome.
