The Master Core (主霊石 Shureiseki / "Masutaakoa"?, "Lord Spirit Stone") is a key item in Tales of Arise. Each core houses a specific element of astral energy.
History[]
Whenever a Crown Contest is held, one of five elements, as well as the master core associated with it, is bestowed upon a Lord. Each Lord is given a realm to extract the energy from and store it within a spirit vessel, which would then power the master core. It is said that at the end of the contest, the cores are gathered to form the Renas Alma, which is then bestowed upon the winner of the contest, who is crowned Sovereign. Though the populace is only told about the five master cores relating to the Dahnan elements, there is actually a sixth core of Dark is held by the Red Woman. All six are brought together after Vholran Igniseri's defeat, and the Red Woman steals away the resulting Renas Alma.
The Forbidden Zone contains more information about the master cores. Underneath a master core's spherical outer layer is a forcefield crystal used for the purpose of astral energy containment and stabilization; this prevents the sentience of Spirits from forming. Each lord can also withdraw astral energy from the stored stock if necessary. The master cores are rendered obsolete with the successful formation of the Renas Alma.
Because master cores store vasts amounts of astral energy, they can respond people, who also contain astral energy inside them, and their emotions as seen in the case of Dohalim il Qaras who goes berserk when his trauma resurfaces.
