The Red Mist Beckons is the Green Wool Dungeon in Infernal Sky II , a CTM map by Vechs.
The Red Mist Beckons is a number of thin gravel platforms floating in the air. The objective here is to make it to the Fleecy box on the other side, while being very careful not to do anything that will update the gravel. If the gravel is updated, it and all gravel blocks on the platform will fall in a chain reaction. Although it may be easy to avoid placing or breaking blocks, ghasts may spawn and blow up the gravel. The Fleecy Box is located near the end of the path, but at the very end is a land of glowstone with loot.
