It was known that aside from the king, there was no one could have such a huge number of magic user, especially when they used them as the attacker in a battle. Raising an army of a magic user was a huge crime against the Holy Kingdom, since all the magic users were under the protection of the Holy Kingdom.
Of course, Koda told this as per Cane's instruction. He was willing to do this because he was racked with anger after learning alpha Colter and Laluna tried to dismiss him.
They should know not to backstab him because he could do the same thing to them. He knew what kind of information that could bring alpha Colter down and ruined his life.
Cane was right, this was the perfect time to deliver the blow. With this, alpha Colter couldn't retort and he could save himself, since the alpha couldn't out him for his own dark and dirty secret.
Everything was about the right timing.
