Kent was planning to send the Sect Master into the tower, where he would extend his torture until the ladies had recovered and were ready to handle him personally.
But that plan was put on hold when space cracked, and through the Void, Ingrid, Lilian, Neomi, and Unity appeared.
Val, Veydris, Sylara, and Uncle Drew were left behind to handle whatever might have been hidden down there.
Of course, everything was cleared out.
These four never planned to come after the sect master, but thanks to Selene and Elsa monitoring the state of Nara and Zaila, they contacted them and let them go and, in place of Zaila and Nara, inflict more damage on the Sect Master.
However, instead of using the harem connection to move to him, Ingrid wanted to show off her skill. So, like a god, space cracked, and the four ladies appeared; he welcomed them.
Obviously, Kent knew what they were after, so the moment they appeared, he knew there was no stopping them.
