The minute Seth walked into Zuroc's tent, he had entered the man's home ground, he had entered into a playing field that was built for Zuroc's victory.
While others saw a normal-looking tent, one whose walls were made of thick cloth, Seth saw different.
To most people, the various engravings put on the tent's walls were just random lines or a sort of decoration placed on it, but to Seth, those were seals.
When Ella had boasted about her kingdom's sealing prowess, it would seem she had forgotten to say anything about the world, because so far, Seth had been encountering seals that left him stomped.
The truth was that if Seth didn't have the enlightenment sphere with him, he would have been a total dullard when faced with the various seals placed before him.
