Behemoth?

Davis saw Myria's pupils dilate while he also felt a chill. The name of that creature just became… bigger and more intimidating, causing him to feel some dissonance with reality.

"Worry not." Unexpectedly, the Frostcloud Sword Empress giggled ever so lightly, "For I have sealed it. However, for you to know about this creature, did master tell you or just… who are you?"

"That doesn't matter. Saintess Lunaria knows about this and doesn't move to evacuate this region? I found the source, and the implosion of the windy ice vent doesn't seem simple. If I'm not wrong, that's where you have sealed the Unfettered Behemoth Ice Fiend, haven't you?"

"How strong is the Unfettered Behemoth Ice Fiend?" Davis couldn't help but interrupt, causing Myria to turn to look at him.
