Ethan naturally requires no further explanation. Up to now, he has "created" quite a few creatures with ice elements.
Lindong's suspicion cannot be completely ruled out either; besides Ethan, she is the only person who could possibly achieve such a feat. These two have comparable mastery in ice elemental magic.
Even Rowena feels that all this makes perfect sense, "Didn't you say before that a 'good story' needs a strong sense of crisis? When Henry VI obtained Balmung, the Empire was suffering a dragon disaster, and you were lamenting finding a suitable enemy."
"But that's not the direction I'm contemplating."
Ethan shook his head; for him, creating a group of dangerous Bigfoot was somewhat too straightforward and crude. Besides, those adventurers from the Hunter's Guild have no grievances against him. He wouldn't deceive them into coming to the northern border just to kill them for the sake of creating a sense of crisis.
