"I am not going to ask for protection. I want to ask for guidance." Walker made his statement. He stood still and did not allow all the manas around to be pulled away from him.
While the true fire sage had immense control of the fire mana, that wasn't the case for the other manas around. Especially for the space mana which had begun to make everything harder for the fire mana to even move.
What Walker had understood about space mana, was that as the foundation for most things in existence, it could put pressure on everything. Putting pressure on how the fire moved was not about controlling the fire mana, but controlling the space that it took up. The space that it existed in.
