"Oh I hope that this thing is not the sage." Gil was being sarcastic since he already could tell that this was not a monster that should be here. That it was not anything that should be here whatsoever.
"It's called an earth brute. But it's not a normal one at all. I am pretty sure something called an earth brute exists as a completely different monster. This one though, was made by the immortal king. He started experimenting."
None of them wanted to hear that the immortal king was able to experiment since it got here. Especially since immortal king was weaker, in a foreign place, and could not easily replenish the undead if lost. Yet here he was playing with multiple undead like they are disposable and nothing threatened him.
"There might be more powerful undead with the immortal king than we realized." this was what they all had expected. But Onyx summed it up out loud to only reinforce that they would have a harder fight than what they expected.
Creation is hard, cheer me up!
