The Mists:

In opposition to the storm cloud’s roiling chaos above, the mists are formless and uniform in colour. Where the clouds have constant motion and chaos, the mist can seem to be uncaring and passive, though the rises and canyons in the mass beneath can seem to form and move with some kind of slow purpose. The mists may not be sending dreadful storms your way, and may not be raining water giving your farm life, but inevitably they will be of great import; all fragments rise from the Mist, and whatever your actions to try and keep them aloft eventually to the Mist they must return.

In addition, those families who drifted far down to the Mist’s edge have come up… changed. On risen fragments have been found whole families just sitting in their houses, staring blankly at the walls. On others, the residents seem to have had their perspective twisted so that that what was once familiar is now strange, yet problems unsolvable by the greatest minds of the tribe are trivially easy to them. Rarely one may fall into the Mists, and yet appear unscathed on a fragment somewhere intact in body but addled in mind - these are the mistborn, and the Mist seems often to reach for them, stretching ponderously towards their fragment like the arm of a laconic giant before falling back down into the blue depths.

It is taught that the Mists are the counterpoint to the Storm’s chaos and uncontrollable energy, instead providing purpose and slow, ponderous force. This can be seen in the case of fragments; lumps of rock birthed from the energy of the Storm which fall into the Mists, which in some way alters them to provide a slow, ponderous purpose and some method of reaching their destination.
