Monster Vault: Threats to the Nentir Vale is a boxed set published in April 2011. It details additional monsters and major non-player characters found around the Nentir Vale region used in the 4th edition rulebooks. It was released after, and designed to be used as a supplement to, the Essentials line of products. The boxed set includes a book describing the monsters and NPCs, and a set of maps and tokens for using those characters.

Terrifying monsters and villains for your heroic- and paragon-tier campaign.

The Nentir Vale - a frontier land sheltered by mountains and strewn with abandoned farmsteads, ruined manors, and broken keeps - is the perfect base for any Dungeons & Dragons campaign.

Monster Vault: Threats to the Nentir Vale presents statistics, tactics, and lore for an array of new monsters that prowl the Nentir Vale, some of which trace their origins back to the earliest editions of the Dungeons & Dragons Roleplaying Game. Other entries focus on campaign villains present in the Nentir Vale region, among them the Iron Circle, the Tigerclaw Barbarians, the Raven Roost Bandits, and several new villainous groups introduced here for the first time.

The monsters and villains contained within are appropriate challenges for heroic- and paragon-tier characters and fit easily into any home campaign, as well as other Dungeons & Dragons published campaign settings. In addition to a 128-page book of ready-to-play monsters and villains, this product includes 8 die-cut sheets of card stock monster and villain tokens and a double-sided battle map featuring four different encounter locations you can use when running encounters.
