Preservation

Preservation is one of the Shards of Adonalsium, inhabiting the Scadrian System. Its Perpindicularity is the Well of Ascension.

It seeks stability and keeping the world and its people in their current state, regardless of if the people are happy with that status quo or not.

In this way it is the polar opposite of Ruin, who seeks change and a breaking of the status quo, regardless of people's wish for change.

Its Investiture takes the form of Mist that fills the world.

History
After the shattering of Adonalsium its shard was taken up by Leras and taken to the uninhabited Scadrian System alongside Ruin, who took Ati as a Vessel.

They knew they could only create anything together, one to preserve and one to destroy, thus they made a pact that Ruin would some day be able to destroy the world that Preservation created.

But Preservation sealed Ruin away in The Well of Ascension, insuring that it would never be able to destroy Scadrial. Though this came at the cost of Preservation's own mind.
