The Caverns of Thracia is an homage to the classic adventure and is a full 5E conversion, plus additional all-new material. A two-volume set presented in a slipcase, these books contain a reprint of the original adventure plus essays from industry luminaries (Volume 1), plus a full 5E conversion of the classic adventure (Volume 2), and expanded dungeon levels and wilderness locales.

Same content as the standard release, but with a limited faux-hide cover.
