Malatium, also known as the Eleventh Metal, is a metal that allows a mistborn burning it to see a vision of possible other lives someone else could have led, and different paths they could have taken. It is similar to Gold, in that it is an external version of the same power. It is an alloy of Atium and gold. Malatium let Vin see visions of the Lord Ruler's possible other lives. It is unknown where Kelsier learned of “the Eleventh Metal”, though he claims it is from stories up North but no Keepers have any records of these stories. It is mentioned that he could have learned about it from Ruin in order to enact it’s master plan.
