Crystons

The seven Crystons are the most sacred artefacts in Riónism, as they are believed to be the physical forms of Saint Seymour and his six disciples, which their bodies transformed into upon attaining full divinity. Each cryston possesses its own unique powers and properties, said to act as gifts to Mankind and exhibit the power promised to those who follow the Creed.

History
...

Theocryst
The Theocryst is the most venerated of the crystons, said to be Seymour himself. It is housed within the Glass Solere atop the Godsearl's Spire, in the heart of the Centrifute. It possesses no elemental affinity, but it is claimed to be the vessel connecting the realms of mortals and gods. As such, it is treated as a well of knowledge, of past and future, of truth and falsehood, and of right and wrong. Only the Godsearl has access to the Solere, and is the only one who hears its whispers.

Crystons Elementalle
The six lesser Crystons, the Crystons Elementalle, are the forms of the disciples that, upon Seymour's transcendence, dispersed throughout the Known World to spread the Creed, following the six cardinal directions of Caddoran tradition. All had amassed a sizable population of adherents in their respective regions. Upon the death of the last disciple, it is said that a miraculous transfiguration took place, and the bodies of all six rose at once and assumed their crystal forms. The followers housed each Cryston in temples befitting their culture and tradition, which soon grew and became Crystforts after centuries of further construction.
