So, was Kratos already in Norse when he got assaulted? Or did he get assaulted in an unknown location and got brought to the Norse when he realizes it after waking up?
Yeah, the realms can't be 5-B under any circumstance just by the virtue of theim having their own Sun and Moon separately. And yeah, the Norse side of things are shown to have countless constellations and galaxies, heck, the Spark of the World has its own galaxies, nebulae and constellations within it that isn't seen anywhere else, not even from Yggdrasil.
That doesn't explain those stars and constellations being contained within the realms tho, certainly doesn't do wonders for each of the Realms having their own separate Sun and Moon.
Also, the realms are repeatedly called "Alternate planes of existence", like Planck said, in the novel.
Pretty much what I stated above. Plus the whole "alternate planes of existence" thing.
Yeah, Jormi encircling the Earth. And some Vanaheim stuff.
Is it me or does Freyr and Freya have a Native American appearance?
