These places are not ones familiar to him, though the words are not completely alien. Well does he know ancient languages, or at least some words within them, and Gaia and Midgard are both words he has passing familiarity with. Though it tells him nothing of where this boy is from, and so Barnabas pull his gaze from him with a single blink, before casting it off towards the bridge.

His behemoth now sits in the middle of the arena. It looks frustrated. He will need to settle its temper later.

"I am unfamiliar with your world. That others would seek to bring behemoths to heel as well... Fascinating."

Especially given that no human could command these beasts, at least not the behemoths of his world. Their might the stuff of legends, that even the most powerful might tremble before them, but not Barnabas. Though the other Dominants should think him mad for achieving what to be thought impossible, it was but a means to an end.

Perhaps a flight of fancy he refuses to admit to.

"Many brought here share in worldly similarities, though not the same world. This is the first I have heard of such with behemoths."
