Expeditions is a collection of additional resources for the Deepnight Revelation campaign. It presents encounters and points of interest that can be inserted into the exploration of any star system and short incidents that may expand into larger adventures, along with three new spacefaring species.

Expeditions also contains four full adventures. In Hillforts of Entrata the Travellers make contact with a primitive race and assist a tribal chief to deal with rebellious subjects. Disputed Birthright is an encounter with a race who apparently evolved from the Droyne. Revelations in Kenvab is an opportunity to learn more about the preceding expedition; a collector has somehow obtained relics once used by its leaders. Dreaming in Real Time confronts the Travellers with a derelict starship still partly in jumpspace, and the waking nightmare of the survivors aboard.
