Bab 556: Welcome to the League of Assassins.

While Ebony was raining spells on Thalia, Blake reminded both Ebony and Ivory about breaking the barrier. So when Ebony was constricted by the ground, and Thalia went over to Blake, he focused on just the vines and the ice barrier since he couldn't fire spells with Blake in the way.

"See you guys later." Blake let out a tired smile as he sunk into another spatial corridor and disappeared out of sight.

"What?!"

  Instinctively everyone turned to the Ice barrier which was now broken in multiple areas. Without thinking Blake went through the portal that took him back to The Square.

"How?" Damon asked the question that was on everyone's mind.

They hadn't seen Blake throw a void dagger so they were confused about how he warped over there.

For a moment, they all forgot that Ebony and Ivory were still present until they noticed the simultaneous increase and decrease in the temperature of different parts of the room.
