In other words, are the white walkers able to cross the Narrow Sea? We do know that they cannot swim, but could the freeze it?

    No proof whether Viserion breathes ice or fire – Dawny33 Aug 28 '17 at 10:26
  • Okay, but the question still remains. The White walkers do have some "icy aura". Could it actually be that strong to freeze the Narrow Sea? – Martin Aug 28 '17 at 10:29
  • I would say the Night King can freeze lakes and stuff. But then he'd have done it earlier in episode 6. I think, unfortunately. This is too speculative of a question and violates our Future Works Policy – Edlothiad Aug 28 '17 at 10:30
  • @Martin Again, no proof to support that the White Walkers or the Night King can freeze water bodies. So, Essos is a safe place for now. – Dawny33 Aug 28 '17 at 10:31
  • I think this is an interesting, but very speculative question – Hans Olo Aug 28 '17 at 10:36
  1. There is no proof that Viserion is breathing ice. For all we know, it can be blue fire. Nor do we have any proof that the Night Walker(s) can freeze water bodies.
  2. Essos is supposed to be a safe place, at least according to what we know till now, this is, that the Dead cannot swim.
  • Who says they can't swim? Just because they waited around the Island till Dany arrived? If that's so, how do we explain them jumping in and out of Ice Holes? – Aegon Aug 28 '17 at 10:35
  • @Aegon Yes. That was the reasoning which Jon and co have given to Cersei. So, that's the only way one can validate this. – Dawny33 Aug 28 '17 at 10:44
  • If they could swim, they could pass the wall at eastwatch from the sea. – atakanyenel Aug 28 '17 at 11:19

    Blue fire? That’s ridiculous! Everyone knows that fire is red! – Paul D. Waite Aug 28 '17 at 11:36

    @PaulD.Waite Also, that fire is green :P Signature flame of Wildfire. – Aegon Aug 28 '17 at 11:50
