Boul Brimgan’s Declaration of War

"This is the worst-case scenario." Hidden next to the ruins of a broken monolith, Rhanalla's body trembled in fright. Originally, the Boar King only terrified her. Every time he was in range, her Primary Nature screamed at her to flee far away from him. 

But once he became the Celestial Boar, Rhanalla felt through her Primary Nature one thing: Don't even think about facing him!

This was why every single Empyrean Tusk in the Attributed Region was warning the rest to run away, for they could instinctively feel that the Boar King was becoming more and more terrifying.

It had been a mere two thousand years since the appearance of the Boar King. But in that short duration, the Empyrean Tusks living on Sumatra had evolved to instinctively fear him. This fear existed so that they wouldn't be foolish in trying to face him and instead would flee the moment they sensed him.
