Through the research of the ancient Caorrn Relorians and the guidance of two of the few living Dualgrounded, the Sons of Plunder have succeeded where many have failed. Aelirtras Venefircra, translating, albeit roughly, to 'Sacred Strength of All That Is.' is a new breed of magic depending entirely on the presence of a natural Weave and the performance of a complex and powerful ritual requiring a truly massive energy source. Currently, only two sources exist capable of producing such power: Plex and the Outerverse. AV is a magic that takes the abilities from the Perfect Leirra, original source of Creation, and Neirron, original source of Destruction, to actively alter reality through an effect similar to a progressed version of the Epoch Circles used in False Heaven. It allows the user to create temporary worlds, outside of any plane, that are tied to the caster's life. If the world is forcibly destroyed, the caster is so destroyed. Travel in and out of these worlds is governed entirely by the creator, and within these worlds the caster can fight at their utmost peak of power, heedless of the toll such an act would normally take upon their body and spirit.
However, creating these worlds is a massively difficult task, and even those with the Aelirtras Venefircra often cannot accomplish such feats alone. Thus bonds between the caster and others become even more important. For some, this is a loved one, trusted to the ends of Existence, for others a close life-friend such as a pacted spirit or animal. Absolute trust is required for the two to remain in sync, or else the world will destabilize and all within it obliterated. It was for this reason that the Orion was originally created, so that the predecessors of Eli and Ararus could pass on their powers completely, rather than the absolute complete copies as was granted to the two Embodiments.
Within these worlds, anything goes. It is the most absolute reflection of a caster's imagination possible; the complete creation of a new world and all the laws and effects therein. The laws governing that outside the world's boundaries do not exist within, and all is left to the caster's decision upon creation of the world. Altering these worlds after creation destabilizes them, ending in the same result as if the trust between caster and supporter(s) wavered.
Magic such as this requires massive amounts of power, and so is not capable of common use. In extremely rare cases, very small worlds can be sustained by a source other than the caster and his/her/its supporters, but an act such as this is immensely difficult and requires the source to have semi-sentience at least, making it just as risky as it is difficult.
