Although this is advertised as an adventure, it's really more like a mini-setting. There's an overview of the history and geography of the region, a recap on recent events, and a breakdown of the various political factions (secret societies), as well as a handful of new abilities (one power, one Edge, and two Hindrances). There are also six archetypes (each offered as two versions: "standard" and "horrid secret").
The setting itself is a bit like a blend of French Revolution, Bram Stoker's Dracula, and Brotherhood of the Wolf, set in an alternate history with heavy gothic overtones and vampire aristocrats. The adventure part is split into three acts, each of which spans two pages, and I'm pleased to see it makes extensive use of Savage Worlds mechanics like Chases and Dramatic Tasks.
Overall this is a very cool product that offers us a taste of great things to come.
