From publisher blurb:
The overcast sky and dusty road are working in concert to make for a truly dismal day. It’s almost a relief to hear something out of the ordinary, like a wailing cry of panic and a harsh, coughing roar. Looking up to the clouds, a thin human figure hurtles down, chased by a savage beast with reptilian wings. But looking up past the two is an even stranger sight...three mighty isles loom out of clouds, impossible and yet somehow real.
K3: To Bring Down the Sky is a site-base adventure built for characters of 4th level, where the players roam three small islands in the sky formerly owned by powerful wizard, Gerlia of the Winds. As the players travel they are witness to a wyvern savaging the wizard’s apprentice as he falls. Either talking to the apprentice Hugo or looting his corpse brings the players up to the sky. The islands there are slowly coming down, panicking the servants of the wizard as her machines and former allies run rampant.
