The manse’s structure concentrates elemental Essence so strongly that every room is overwhelmed with its aspect. Light changes color as it enters, as do any objects left there for long. Moreover:
Terrestrial anima banners of the corresponding element cannot damage the manse. The manse’s energies absorb their physical power. People, however, are not immune.
Appropriately aspected Charms and spells—including the abilities of elementals, Terrestrial Charms with the Elemental keyword, or spells directly affecting the element—have their final cost reduced by (manse’s rating) motes, minimum 0.
Children of Dragon-Bloods conceived within the manse gain a +1 bonus to their chances of Exaltation, as if a parent had high Breeding (see The Manual of Exalted Power—The Dragon-Blooded, p. 106). This increases to +2 if the child is brought to term within the manse. The Exaltation’s aspect is hardly in doubt.
The hearthroom of the manse is in a state of dangerous elemental upheaval. It’s an environmental hazard with a Damage of 3L/action and Trauma of 5, ignoring armor. The hearthstone bearer is immune to this effect, but probably had trouble attuning in the first place.
