The Hearth Crystal bound to a Amarata Hearth is something many Umbakians carry with them during life now. It has taken on some of their aura, and allows for them to personalize it and be buried or burned with it wherever they may fall and whoever oversees that. It is not considered a requirement for the afterlife, but it is considered expedient to return to the family hearth there – adding their energy to that of the living family hearth for those that come after them to draw upon.
The Hearth Crystals are the key to channeling the power of the hearth, and they must be attuned by being in the presence of the Amarata Hearth for a day’s fire duration. It used to be only nobles and those questing used the crystals and benefited from their protection, but now any of the larger extended family can – this came with the burial custom change in CY 8200 becoming a norm for Death, Burial, and Cultural Observances.
Opposition: The Hearth Crystal has always bothered some purist Umbakians, as it borders on Blood Magic rather than strictly religious bonds.The bonds of Conviction are what the purist believe should be used – it requires greater commitment (though less money) to achieve something similar.
