After Miguel and Elias agreed, they all showed Axel the inside of their wrists, and the Warrior Spirits who were unable to see the Divine energy could simply see the golden runic symbols that were being drawn on their skin appearing bit by bit.
Axel used the runic symbol of sharing and the runic symbol of vision and he linked them to his vision of his divine wolf in an intricate design.
Since he had gained all this knowledge after that the Creator had used his body as a vessel last time, these runic symbols seemed to appear of their own accord in his mind whenever the situation called for it.
He then explained to everyone: "The Werewolves have a silver aura around them, and those who have corrupted souls have black spots in their silver aura.
On the other hand the Knights of Darkness have a totally black aura, more or less intense and thick depending on their level, and at least now you will know right away who you are fighting against."
