In the Mirror Realm, Caleb's eyes were just fixated on the mirror-like sky that reflects everything on the ground in deep thought. If there are really nine paths in the past, then something big must have happened that caused their disappearance. For example, as of now, there are seven gods worshipped by the people in the City of Phenos. It's not far-fetched that other kingdoms must be also worshipping the seven gods.
As he thought of this, Caleb reaffirmed his thoughts. This world has a lot of undercurrents that he couldn't fathom with his current strength... Then there was also Shu's proposal. Join the Fool Kingdom? He didn't even know what kind of kingdom was that. Who is sane enough to call their kingdom by the name of the Fool? Perhaps their king or god is a Fool??? Now, he understood that it was only Shu's whim to invite him to join. Might be because of the combat prowess he displays at his age.
