I hope we don't have another fire/fight. But I was watching a Pokétuber's stream, and someone pointed out that the new region looks just like England if you turn it upside down. But I think Fenrir could be an inspiration for the wolf hinted at in the logos. Fenrir does have siblings, so if Fenrir is one of them, the other could be Hel or Jörmungandr

EDIT: Plus there is a Big Ben-like place, which I wonder if ti will be a gym like Lumiose Tower is.
