Expedition to Undermountain
Expedition to Undermountain is a generic setting adventure module for the Dungeons & Dragons (D&D) roleplaying game published by Wizards of the Coast in 2006. The book contains a 221-page adventure campaign setting designed for 1st- to 10th-level player characters using the D&D version 3.5 rule set.

Plot summary
Expedition to Undermountain presents an adventure campaign designed to cover a number of levels of play. Undermountain, as it is presented here, is a huge adventuring area for any D&D campaign, containing nine main levels and more than twenty sublevels, connecting to more extensive dungeons and caverns, and ultimately to the Underdark. The book treats Undermountain as an unexplored underground region, and provides plots, power groups, and lore to enable a Dungeon Master to detail any corner of Undermountain to create a long-term adventure setting.  Encounters are presented in the book, which are designed to take a party of player characters from 1st level to 10th level. With an appendix it also describes a set of new creatures, such as the Eyeball Swarm, and new items, such as the Crown Adamant.
