So how does this travel work considering Fenris is a being that exists in the ninth dimension and creates less powerful avatars throughout the lower dimensions in order to interact with its peoples?
Well, I would imagine that without dimensional limits, it might feel like there's an abnormally large amount of room to stretch within it's avatar, and can comfortably fit more of itself within it.
But at the same time it would be thrown off kilter by the absense of the reliable stability a dimensional fabric provides.
Of course, should it choose to add more of itself to the avatar and leave it there as it returns to the third dimensional layer, the avatar will likely be affected.
In fact, I will bet that it might go through some kind of process or experience should it's creator attempt to keep that extra amount of themself in their avatar.
An idea I have is that maybe you could liken it to a higher dimensional version of the process tier threes go through in becoming tier fours if you want? Of course it's your character, so it'll be interesting to see what you come up with.
What do the rest of you think about this?
I'm asking because it would be interesting to hear how this might fit into existence.
