Right. [ legendaries with fog brain... ] If I am honest I do not really think it is Xerneas? Not enough to say it's any of them really. Was just an example and a possibility.

But if there really is a legendary or a mythical in the forest, and they are affected by the mist. Then I verrrrry much hope it is not Xerneas, just as an example.

[ and maybe this time when the telepathic message comes through, Firoza she'll note that the unfamiliar name comes through more as the concepts underlying it than just the sounds that comprise it, forests-life-unending-overflowing. ]
