Both groups endured the attacks of the beastpeople for well over fifteen minutes, facing relentless attacks.
Grey was not under much pressure compared to the rest of the people. Although he could not use his space element, he was still able to fairly move properly thanks to his years of use of the gravitational force field. One has to remember he trained on multiple occasions while mastering this technique. It also helps that his physique is unbelievably firm, which made most of the effects of the restriction limited on him. To be honest, if he wanted to kill one of these Peak Sovereigns with a sneak attack, they would not be able to react before his attack connects. Even if the Sovereign manages to survive the attack, they would end up seriously wounded and incapacitated.
Silvan also had enough strength to fight back against the Peak Sovereigns attacking them, he just focused on defending since it was the best course of action at this point.
