An interesting oath indeed, goodsir Iggy. For all that he can maintain the aloof and stoic façade normally, mind-linked like this it's rather a bit harder for him to fully hide his amusement.

It's also a bit gratifying, yes. He helped Magneto build this sanctuary for their people; even knowing it to be a sin, Exodus cannot help but feel a bit of pride at the awe Iggy is experiencing to witness it now.

You are wondering, perhaps, how an object of this size is not noticed on Earth? Mind-linked as they are now, even the passing flicker of the question is enough for him to pick up on. Our leader possesses complete control over the electromagnetic spectrum. He has personally cloaked Avalon in a mantle of his own power. No telescope, no radar, no system on Earth can detect our sanctuary. Until closing to within a certain distance we are invisible even to the naked eye. As you may have noticed.
