What do you think is the differences in souls?

[TheMightyMollusk]

A dragon's aether is stored in their eyes, and Thordan and his Knights Twelve devoured Ratatoskr's eyes to gain her power, so her soul might not have even made it intact to the lifestream. Which is a lot more disturbing written out than it was in my head. Bahamut and Nidhogg could be out there, though. Some of Nidhogg's power is still bonded to Estinien, but we did explicitly see his spirit move on after the Final Steps of Faith, so who knows.

Of course, all of this only applies if dragon souls follow the same rules as everyone else's, which we just don't know.

The main soul-related question bouncing around my mind lately is the realization that, if souls are cycled within the lifestream of the nearest planet (which is usually the one they died on), somewhere out there are regular-ass people with Bahamut and Ratatoskr's souls.

Are we absolutely certain souls from outside Eitherys are reborn as native species though? Can dragons from the Dragonstar not just reincarnate as another dragon if they die as Eitherys? If not, honestly that just adds a whole new layer of fucked up onto the cake. I know I wouldn't be pleased to be reborn as the species that arranged my death, especially if I happened to be something as prideful as a dragon.

The way I see it, either Ratatoskr passed into the Lifestream when Thordan and his Knights Twelve died or Ratatoskr is quite literally a part of every soul in Ishgard now. Which is heavily ironic, now that you think about it.
