Herman immediately decided to consider this young mage a Battle Mage from Gaugass, accusing the Mercury Tower of harboring a Battle Mage. By using the hatred of the Black Tower, he would start a war on a shocking scale. At that time, whether it was in exchange for his achievements or through something else, he would be able to get the Gold Forest Plane's coordinates.
As for whether that young mage actually came from Gaugass, Herman simply didn't care.
In any case, once he was locked in the Black Tower's Obsidian Prison, the methods of those crazy mages would force him to admit any criminal charges that they wanted.
At first, Herman had felt that his plan would be sure to succeed.
The only mistake he made was to underestimate that young mage...
The problem was that this one mistake was a huge one.
