"Void, Alice, and Klaus, you three should deal with the weaker ones in that area and come help us as soon as possible. Myself and Reynolds should be able to hold them back until you guys come." Grey shared the task within them. From what he could sense, the last formation laid out by the Gnomes was the one here, so the others did not have to worry about getting caught in any trap formation which is also made them aware of.
They could not wipe out the weaker Gnomes without the stronger ones sensing their presence, so it was best for Void, Klaus, and Alice to wipe out the Gnomes below the Sovereign Plane while himself and Reynolds dealt with the stronger ones.
