A Spiritual Sage was someone with abilities under space who could travel through wormholes and use their short-range spatial manipulation to 'catch' things through 'gaps' in space.
That was something that Minos' enemy had been using for ages to save Abe, but it could not be seen as him using his own powers against the local forces. At most, he was hindering Emperor Stuart's movements but not acting against this guy.
What would be considered a hostile attitude, let's say, would be him using this ability directly against Minos. Or something more obvious, attacking the local forces members in favor of Abe and his group.
So Minos wanted to force this man to use his abilities on a level beyond what he had done so far by using these high-level Spiritual Saints to attack him.
Through this, the Spiritual Sage would have to choose to receive the attacks from dangerous people or escape and risk losing sight of Abe.
