Well, starting academy does not even need destiny. Even then if she develops 'greatest sorcery academy of all time' it would ask her to able at least ability to perform celestial circle sorcery (basically re-open first age academy which is able to teach solars, sidereals and lunars celestial sorcery besides terrestrial).<br/><br/>So, my own idea for destiny 5 for concept; 'greatest DB sorceress all time' is for single fact; she surpass her limit as exaltation somehow to able do celestial circle sorcery (if said it is impossible for DB to perform celestial circle sorcery because low essence pool, then note that Scarlet Empress was able to do same by having first age artifact; Birgitte's Cape, the first solar sorceress in recorded first age history). But my char case she does not depend artifact to pull it off; but somehow break the limit (either get it as boon from very god who is responsible creating DB exaltation or she finding way around it by increasing her own essence self to celestial levels).<br/><br/>At least this is my idea how my destiny 5<em>could</em>work, also I find it as interesting irony that a DB is teaching solars how use celestial circle magic (she ofc cannot teach solar circle magic but she would be long term mentor in sorcery).
