Now, I'd noticed when Aurora Fryevia came out that the ability that unlocks Aurora Storm was Knowledge of the Past, and Frye's is Knowledge of the Future, indicating some kind of time travel, or at least vision or....knowledge. And it just occurred to me, with the Fryevias having a bonus in the Exeggutioner trial, that maybe Fryevia has some thing to do with Esther's story.

And while we're here, with Elena boosting Aurora Storm, what does she have to do with Fryevia...or with Esther?

Edit. Okay, well going to read Esther's in game background story, I guess that answers that.

Long ago, when her world was in peril, Esther attempted to seal off one of the Great Destroyers threatening humanity. Although many assumed this resulted in her death, the sealing ritual actually flung her to the present where she continued her never ending fight against evil. However, upon arriving to Sylvie's timeline she learns that the seal has weakened due to the passage of time. Now Esther will be forced to face off against this powerful foe once more.
