The Aetheract
The Aetheract is a powerful tool created by the Theurgy of Threia. It exists in it's own pocket dimension, transcending through layers of the multiverse to draw upon the Aether and funnel it through an array of Aether Shards for two distinct purposes.
 * 1) The Aetheract grants to the common folk of Threia the ability to use sigaldry and runes to affect change by enacting a language and a set of formulaic rules that affect change through the Aether.  Thaumatic Arrays and magical formulas can be drawn, spoken or inscribed to create enchantment or cast spells.
 * 2) The Aetheract can imbue some chosen people with a godlike power that grants them unfettered access to the Aetheract and it's infinite computational power.
