The comparison to the Shinryu thing has me wondering if it was actually a preview of their creation magics? That Lahabrea created an arcane entity that he and Igeyohrm channeled.

Would not only parallel a simialr event in Akademia Ayndyr but also explain the name, as it would be something an Unsundered Ascian (who by definition would be closer to their PRIME then sundered ones) could be capable of.
