King Aeon had purposefully neglected the issue with the dark magic, though the rumors about it had spread across the continent and this sent a wave of fear among the people. He simply pretended it didn't happen, which was expected of him, since Cane had his own suspicions that the King was behind it all.
There was no way Alpha Gill dared to act so boldly until he fostered a dark sorcerer without a common goal between them.
Alpha Gill's aspiration was not that high and he didn't have any ambition that included dark magic and put his whole pack in jeopardy by engaging in such taboo things.
However, it was a different matter completely if you take the King into consideration.
"My King, you are wise and fair. I have punished the people that touched dark magic. Isn't it only right to call Alpha Gill from Riverside to question the activities of dark magic in his pack? I heard many rumors about it on my way here."
