A Contest of Nisse and Release
A manse is a structure of occult architecture used to cap and channel the essence of a demesne. The Demesne’s energies are geomantically focused by the manse into the creation of a form of crystallized essence called a hearthstone and also to power the various features of the structure itself.
Exalts and other essence-users replenish their personal reserves of essence more quickly inside a manse, and to a lesser extent from carrying a hearthstone against their skin. To gain essence from a Manse, an essence-user must be attuned to it. Attunement to a manse requires the permission of its owner.
