Unsettled: Strannos

From BoardGameGeek:

Take refuge in clockwork stone shells, and endure the heat of floating lava rivers in this fiery wonderland of timed maneuvers and variable gravity. Unsettled: Strannos is the 5th planet box for "Unsettled". This swirling jumble of floating stone, lava tubes and fire are held “together” by a weak gravity and atmospheric shell but never form a greater whole. An explorer standing on a horizon-stretching chunk of rock can observe thousands of similar stone continents floating overhead and across the horizon, rivers of lava floating among, around, and over them as if inside a planet-sized lava lamp. Up and down have no meaning in this constantly shifting world of hellish heat and stunning spectacle. To navigate this environment is to risk death.
