From publisher blurb:
5th Edition Mini-Dungeon for four characters of level 7
Long before the first dwarf delved or the eldest elves walked among primeval woods, a race of beings had already spread among the stars. These enigmatic creatures may yet dwell somewhere beyond the sky, but none have ever set foot upon this world. They did not have to. Not when their ships could make the journey for them. An inquisitive people, these Far Ones were great students of arcane science and natural philosophy.
The probes they designed were meant to visit distant worlds, record the dominant life forms they discovered there, then move on to the next. One such probe just woke from its long slumber. In the process of reactivating long-dormant systems, this ship has managed to catch the attention of less exotic natural philosophers in the region.
