Being an Akashic-Deviant would, in my humble opinion, likely require the intervention of some great Divine spirit, the imparting of knowledge from the dawn of existence... :sun Sounds like a job for an Ouramancer! At the very least, ancestors and gods can be consulted on such things.

It seems all of our characters might fit together, or at least that the Outsorceror and Shifter's determined inferiority-complex guy would both have reason to seek out and make use of my Ouramancer's talents! Maybe they've all met and become acquainted before the story begins, each of them with their own goals and long-term issues that play off the others. :) Things are turning out nicely.
