"One of the gods of this place." Bayek does not sound at all pleased, scowl firm on his place. "If that is your aim, explain why you have brought me here twice now."

He falters a little bit, because he's not so sure about having gone home. What if it was returned memories instead? The ambiguity of this whole experience is frustrating.
