'''Sunhearts''', known as '''cinderhearts''' when corrupted, are a form of Investiture on [[Canticle]].

== Acquisition and Properties ==
Sunhearts are made from people who are condensed into power cells while being between [[Canticle]]'s sun and the core of the planet.{{book ref|tsm|12}}{{book ref|tsm|40}} How much energy a sunheart is made with depends on how [[Investiture|Invested]] the person was, but most of the energy comes from the superheated energy of Canticle's sun transferring to the planet's core and the person's soul resisting that energy.{{book ref|tsm|16}}{{book ref|tsm|21}}{{book ref|tsm|24}}{{book ref|tsm|40}}{{book ref|tsm|45}} Those made from [[Threnodite]]s on Canticle are made with at least two hundred [[BioChromatic Breath|Breath Equivalent Unit]]s.{{book ref|tsm|24}} A normal Threnodite from [[Canticle]] has only one BEU,{{book ref|tsm|23}} which suggest that for every one BEU a person has, two hundred BEUs of Investiture from the sun fills the sunheart.

Sunhearts are cylindrical lumps of what appears to be smokestone eight inches (~20.5 cm) tall and a few in diameter, and feel like glass.{{book ref|tsm|20}} They emit a deep red light.{{book ref|tsm|24}} Sunhearts can be broken apart like resin and each piece will continue to glow.{{book ref|tsm|24}} Once depleted, they resemble dark glass or gemstones, with bumps on their surface.{{book ref|tsm|8}} Some sections can resemble a screaming face.{{book ref|tsm|20}} Despite their condensed heat, they can be carried safely.{{book ref|tsm|8}} They will float to the top of magma.{{book ref|tsm|13}} Charged sunhearts are considered alive by the reckoning of Investiture.{{book ref|tsm|23}}

== Energy ==
{{image|UninvestedSunheart.png|side=right|width=300px|height=300px|An uninvested sunheart}}
Sunhearts are stable forms of condensed energy and are able to act as batteries or fuel.{{book ref|tsm|8}} This can be strong enough to power entire cities.{{book ref|tsm|11}}{{book ref|tsm|19}} Once all of the energy has been expended, the core will dim.{{book ref|tsm|8}}

Heat and Investiture can be transferred in or out of a sunheart, though a [[Connection]] to the person who made it is required to transfer energy into it.{{book ref|tsm|33}}{{book ref|tsm|24}}{{book ref|tsm|36}} When taking in Investiture, sunhearts will filter and purify it and will take corrupted or undesired Investiture first.{{book ref|tsm|24}}{{book ref|tsm|36}}{{book ref|tsm|37}}

=== Recharging ===

If not depleted, sunhearts can be given a small amount of heat, but this normally doesn't give it very much energy.{{book ref|tsm|21}}{{book ref|tsm|23}} If a depleted sunheart is left back into the sun of Canticle, it will not recharge.{{book ref|tsm|22}} If there is still some energy in them, sunhearts can be recharged in the sun, since the soul is resisting the energy.{{book ref|tsm|45}}{{book ref|tsm|47}}

== Cinderhearts ==
Cinderhearts are corrupted sunhearts made from a special Investiture.{{book ref|tsm|45}} These can be used to create [[Charred]] by stabbing a person in the chest with it.{{book ref|tsm|45}}{{book ref|tsm|24}} Once the cinderheart is inserted heat will begin to flare, causing sparks and flames to spray out as the body is burned.{{book ref|tsm|50}} The person's pectorals, rib cage, and heart will burn away, leaving seared and blackened skin.{{book ref|tsm|1}} The cinderheart will then radiate from the center of the cavity.{{book ref|tsm|50}}{{book ref|tsm|25}} Through their cinderhearts, all Charred are Connected, and can feel the presence of other Charred.{{book ref|tsm|50}} Cinderhearts devour the Charred's [[Identity]] and [[Connection]] in a manner similar to [[Yelig-Nar]].{{wob ref|16297}}

Cinderhearts resemble a glowing ember that emits a bright light.{{book ref|tsm|4}} If the corruption is removed from a cinderheart, they will glow a soft red-orange.{{book ref|tsm|29}} When a cinderheart burns something, it will continue to smolder for a long time.{{book ref|tsm|42}}

== Usage ==
Sunhearts are used by the people of [[Canticle]] to power their cities and to an extent, all their individual ships.{{book ref|tsm|11}} It’s also likely they use sunhearts to power their guns. Sunhearts can also be used as explosives, which can be strong enough to destroy a ship.{{book ref|tsm|42}}

Sunhearts can have slivers shaved off, which keep some Investiture and can still be used as a power source.{{book ref|tsm|24}}{{book ref|tsm|48}} Charred can use sunhearts to store a little bit of their Investiture, making them more independent and able to think logically.{{book ref|tsm|24}}
