A rare and precious metal on Scadrial, the condensed physical form of the Shard Ruin's power. When burned by an Allomancer, atium grants a brief window of perfect precognition - the user can see a few seconds into the future, perceiving shadows of where opponents will move. The Lord Ruler hoarded the world's atium supply in the Pits of Hathsin. Atium is one of the two god metals in the original Mistborn trilogy (the other being lerasium, the condensed form of Preservation).
