Hmmm!
Tumko's isolation array had been enhanced with other features. A distinct mana pulse was spread as the feature activated.
The golden runic chains sprouted from the ground and bound Kirin as soon as Eren finished declaring his intentions. Her arms and legs had been tightly secured in these chains, making her unable to move.
The same thing was about to happen with Alephee as well. But she got away from the chains and just flew in the air. She used the Solid Spark as her weapon to defend herself from multiple chains trying to trap her.
Eren came to realize Tumko's team didn't want to fight off with Kirin or Alephee. Tumko had kept Jaad Ugar, Teer Maar, Kavach, and Hath Oda placed at the four corners of the isolation dome to serve as the operators for the array eyes.
Kirin was being tied to her spot by Jaad Ugar and Teer Maar controlling the runic chains through the array eye. Whereas Kavach and Hath Oda attempted to incapacitate Alephee.
