The second phase of Project Aleutian is cloudfall. After the first core crystal is removed, the stone cloud enters landfall and begins to descend toward the ground. A card is drawn from the stone cloud display deck to determine what shape the stone cloud display takes. Once it is revealed, the players must race to get resources off before enough core crystals are removed and it crashes into the ground.  

Any cards in the stone cloud display that aren’t partially covered by other cards are considered “available” to all players, regardless of where they are seated relative to the display. Other displays continue to behave as normal when determining if a card is available or not. 

During cloudfall, players start to accumulate cards aimed at gaining prosperity (or victory points) in a last-ditch effort to push for victory. The game ends immediately when core crystals equal to the number of players plus 1 have been removed from the main displays (purchased or discarded).
