: Nyx didn't create Tharsis. It was a result of the battle
: between Nyx and Wyrd, a wound on the planet.
But Nyx made that wound. Wyrd created the world in the battle, and Nyx wounded the world with Tharsis.
: OMG, Forrest tries to apply scientific reason to a
: fantasy world! Stop it!
Eh? I don't see anything vaguely scientific in there, other than basic logic, which isn't neccesarily invalid in a fantasy world - the fantasy world just has different universal laws which the logic works upon.
I mean, who's to say why gravity pulls things down? It's magic. Sure, Einstein explained that it's actually depressions in space-time, but why is that space-time depressed? Why does it exist at all? Well, quantum theory says that there are some timelines where it isn't depressed, or it doesn't exist. So the entirity of the multiverse is governed by the laws of probability. But who wrote the laws of probability? There is no time "before" probability, so nobody in the universe could possible exist to say "ok, that's the way things work". But someone OUTSIDE the universe, maybe; our entire reality could literally be the dream of some 'god', or a "computer simulation" (or equivilant) that it's running.
(And before someone jumps in and says the laws of probability predict their own existance and thus created themselves, that's circular logic, which is no logic at all).
So the laws of any particular universe are essentially arbitrary, and in the fantasy universe of Myth, those laws include gods and magic. But the same logic works everywhere, as logic is just a method of thought, independant of the rules that it's working within.
