Nagubal's smile fades for moment, and he shares a look with Trenyk, who can only shrug, and Znelaar, who nods and steps forward, before 'speaking' to the strangers. "You entered our world through the Oldkathe, what you might call our world's center, or origin. Such a thing happening would seem to imply that the First Shaper left the key to enter this world with you, or your forebears, so it is surprising that your magic and even your language would be so different from ours."
Nagubal nods, and speaks again next. "Please, come with us. The other Shapers here in the mountaincourt are all in a fuss about your arrival, so we need to go explain the situation to them."
After a moment he realizes that the situation hasn't been explained to him yet, either, and so he asks, "Where are you from, anyway, if you're not from the Old World?"
