Elena understood many things about Aura. After all, she specializes in the Historical Study of Aura. She earned her diploma due to her stellar thesis paper about Aura and its application in the Ancient World.
That being said, she was not arrogant enough and state that she knew everything there is to know about Aura.
The only one who can claim that was her lover, who was a glorified Aura Prince, and thus has an in-depth understanding and knowledge towards Aura and life itself in general.
Ash becoming an Aura Guardian was probably a milestone in their relationship. It showed the extent of Ash's devotion towards her. Becoming something that Elena was thoroughly interested in, it was Ash's way of telling her that he would become anything for her.
To this day, Elena has yet to answer that gesture with her own.
Still, due to her interest in Aura, she could not help but watched her sister as Ash teach her how to become an Aura Guardian.
It was a spectacle that Elena would not miss.
That being said, Elena was slightly jealous of her elder sister.
Elena could remember, in great clarity, the many stories her mother told them about Aura Guardians, Aura Knights, Aura Sages, and Aura Princes in their childhood. Elena had always been wide eyes from the tales of their exploit, of how they maintain the balance of the world.
Elena had once dream of becoming one.
Though she was technically capable of using Aura now, the fact remains that she was not a true Aura Guardian.
She was the mistress of an Aura Prince. The Aura at her disposal belonged to her lover, and though she was blissful and ecstatic of having his aura in her veins, Elena wanted to experience using her own Aura.
Still, she was satisfied with the cards that she was dealt. She has no complains. She doesn't have the right to have one.
That being said, watching her sister become an Aura Guardian was an enlightening experience. Ash had told her the basic training that all beings with the capacity to harness Aura must undergo to fully use Aura.
Seven steps that one must learn to fully be recognize as an Aura Guardian. Seven steps buried through the ages as Aura Guardians became nothing more than myths and legends.
Watching those seven steps take place in front of her was sight to behold.
Though she wonder, how long will her sister take to complete those steps.
Ash completed it under a single night. In a single night, Ash became an Aura Guardian.
Elena wondered how long her sister would take before she becomes an Aura Guardian.
With that in mind, she continued to watch her elder sister's training.
