Descent into Verdant Shadow

Publisher's blurb: A Starfinder Society Scenario designed for levels 3–6. The Ice Wells of Aballon are half-frozen jungles that line the planet's deepest craters. Preservationist Xenowardens monitor these sites of natural splendor, and they have recently granted the Starfinder Society exploration rights to the Ice Well known as Gullet. Venturing deep below Aballon's surface, a group of Starfinders quickly uncover a threat to the verdant jungles and a growing sickness that could threaten the rest of the planet.
