[Chapter] 77 [Entry] 
Looking back, we should have been able to see the connection between the mists, Allomancy, and the power at the Well of Ascension. Not only could Allomancers' vision pierce the mists, but there was the fact that the mists swirled slightly around the body of a person using any kind of Allomancy. More telling, perhaps, was the fact that when a Hemalurgist used his abilities, it drove the mists away. The closer one came to Ruin, the more under his influence, and the longer one bore his spikes, the more the mists were repelled.
