Lerasium was created by Leras.[[21]](https://coppermind.net/wiki/Lerasium#cite_note-Arcanum-6046-21) Rashek collected the beads,[[22]](https://coppermind.net/wiki/Lerasium#cite_note-Arcanum-140-22) after taking the power of Preservation at the Well of Ascension, and used them to entice foreign kings to become his allies.[[23]](https://coppermind.net/wiki/Lerasium#cite_note-Arcanum-8001-23) He left two beads near the Well, for reasons unknown.[[24]](https://coppermind.net/wiki/Lerasium#cite_note-MSH-2-1-24)

However, neither of these beads were used prior to the fall of the Final Empire. One bead was fed to Elend to save his life after being attacked by Leras, whose hand was directed by Kelsier, in an attempt to prevent Vin from releasing Ruin from the Well.[[25]](https://coppermind.net/wiki/Lerasium#cite_note-The_Well_of_Ascension-58-chapter-25)[\[26]](https://coppermind.net/wiki/Lerasium#cite_note-The_Well_of_Ascension-59-chapter-26)[\[27]](https://coppermind.net/wiki/Lerasium#cite_note-MSH-2-4-27) The other was stolen and consumed by Hoid, after he used the Well to transition from the Cognitive Realm to the Physical.[[28]](https://coppermind.net/wiki/Lerasium#cite_note-Arcanum-12210-28)[\[24]](https://coppermind.net/wiki/Lerasium#cite_note-MSH-2-1-24)

Wax was later able to split ettmetal using trellium to create more lerasium, which was later used by Wax and Wayne, creating the first known Mistborn since the Lord Mistborn right after the Catacendre.[[7]](https://coppermind.net/wiki/Lerasium#cite_note-The_Lost_Metal-71-chapter-7) Kelsier wishes to use it to create an army of Mistborn to fight against the armies of Autonomy, though Harmony rejects these plans.[[29]](https://coppermind.net/wiki/Lerasium#cite_note-The_Lost_Metal-epilogue-4-29)
