"Hello, Superman.. Hello."
Unless (benevolent ruler) Abaddon was able to lay the smack down on the Elder Dragons, since he didn’t leave in the opposite world, they would have consumed the huge amount of magic the races of Tyria were using, and most likely destroyed the world.
There is one thing you forgot. When the gods granted magic, they granted it to everyone, not just humans. So in opposite world, the gods would have first sealed magic further, then they would have released a large amount of magic into the world.
But would the Elder Dragons still consume magic in this world? Or would they create more of it somehow? I dont like the “Gods are Elder Dragons” theories, but this got me thinking. Maybe the whole “the Gods sealed away magic” thing is a metaphor for/related to dragons consuming the magic? Probly sounds better in my head.
