The main barrier was still up, so it was no problem for Lana to get around. She teleported all around using her movement technique while helping any of her subordinates that needed it along her path to search for Tera.
Lana thrust her hand out and produced a cubic barrier around one of the eater's heads that were bearing down on a lone priestess and crushed it instantly with a clench of her fist. She teleported around again and helped another group that was surrounded by shredding their attackers with a wave of blade-like panels.
Her attacks were unnamed, yet they displayed her mastery over magic clearly. Whereas most barrier users struggled to use their powers for anything but defense, The empress and her daughters did so with ease. It took a lot of effort and control to mold the shape of barrier magic into one suitable for attack, but the current royal family was the most skilled at this than any other in the past five generations.
