Emery returned to the shrine and quickly told the High Priestess about how the legendary sword was apparently unwilling to be wielded by him nor Arthur. The reason he came back apart from checking on Morgana again was also to ask more details and specifics about the vision Gaia had shown him, which the High Priestess also had.
"What exactly do we need to worry about and when will it happen?"
The vision given to him had specifically shown the importance of the sword. Therefore, Emery believed being able to wield its inherent power should be the main key to face whatever it was threatening Gaia in the future.
Unfortunately, the High Priestess told him that Gaia was quiet about this and still hadn't said anything since the last interaction. However, she also believed that this odd situation was a matter of importance because she never found Gaia to be so restless ever since the time she became the High Priestess, which was two hundred years ago.
