The group did not stop there, after killing the Sovereign Gnomes, they headed straight for the Gnome camp, wiping out all the Gnomes there. They returned to the City a few kilometers away from the City.
When the Commander saw them returning, seeing the injured Klaus and Reynolds, he knew they must have fought a brutal battle. When he heard of the outcome of the battle, he was left dumbstruck. One has to know that he was a Peak Sovereign, and had been fighting with these Gnomes for some days now. Even with him present, they have not been able to get a complete advantage, much less kill all the Ninth stage Sovereign Gnomes. Yet, in only one battle with Grey present, they wiped out every single one of the Gnomes. If not for the fact that he sensed the auras of the Gnomes vanishing one after the other, he would not have believed this.
