The Soul of the Skorr (also known as the Soul of Alar) was a vessel that contained the brain pattern of Alar, recorded before his death in a piece of indurite sculpture.
In 2269, the Soul was stolen, which triggered a racial fury in the Skorr, who were preparing themselves for a jihad against the known galaxy unless the Soul was recovered. (TAS: "The Jihad")
It is conceivable that this technology is in some way similar to the katric arks and/or the receptacles.
