Arthur was tired of training.
He spent a millennium training with Ragnar to control his wrath.
At the moment, he learned to do that better than anything else. He no longer lost control — no longer allowed it to control him. But ever since then, he felt like all he did was train.
Master Guffaw was right. They needed to train for the upcoming challenges, but the three days felt like an eternity for Arthur. He was itching for a fight — for the feeling of power that overwhelmed him whenever he released his spiritual energy.
The issue is that every time he released the spiritual energy, it consumed him, almost turning him into energy himself. It crossed the boundaries of his soul and welded Arthur into the world.
Lusica and the others trained in a different path — one that promoted the growth of their souls. Arthur had to train to keep his soul against the overflowing spring in his soul that brought spiritual energy from an unknown source.
It was his biggest mystery.
