|Abilities||Shard of Preservation|
|Featured In||Mistborn trilogy|
While he is still able, Leras appears to the souls of the dying on Scadrial in order to offer some comfort before they move on to the afterlife. He appears wearing a thin wool coat that reaches almost to his feet, as well as a laced shirt and a conical skirt tied by a belt holding a knife with a handle of bone.
He becomes the Shard Preservation through unknown means. As Preservation, his mind was warped to fit his Shardic Intent, making it impossible for him to destroy, only to preserve things as they were. In an agreement with the Shard Ruin, he obtained Ruin's help in creating a planet (Scadrial), in return for allowing Ruin to destroy it. However, his Intent prevented him from actually allowing Ruin to destroy Scadrial. He orchestrated the downfall of Ruin on Scadrial with an elaborate plot to sacrifice himself (since holding Preservation meant he was unable to destroy). He sacrificed his mental capabilities to entrap Ruin in the Well of Ascension, effectively preventing Ruin from majorly affecting the world.
However, Ruin contrived to get Vin to release him from the Well of Ascension. Freed at last, Ruin assaults Leras in his weakened state, killing him. His body then coalesced from the mists, before being buried in ash. Kelsier then takes up the power of Preservation, who then gives it to Vin. She then kills herself and Ati - possible both because she had a bit of Ruin in her and because Preservation had less time to mold her to its Intent. This allowed Sazed to pick up both Shards to become Harmony.
Sazed later saw that Preservation had orchestrated the entire plot from Ruin's imprisonment to Vin and Ruin's mutual annihilation, saving the world.
