The door swings both ways. Avilona was messed up by Kasvarina's mistake. The damaged link drained energy from the plane.
(Also, are we ever going to get an explanation for Gale's ability to ignore all this and just fly with no time limit? Or did that happen and I missed it?)
Now in ZEITGEIST, Tinker found a strange artifact that gave him his powers. (Called a Godmind Orb, as a vague suggestion that it was something psychic from the time when the Gidim were afoot.) Gale . . . if I had to have a reason, it's because of celestial fluke. She was born under Avilona, and grew up in anti-magic Danor so the minor air energy that was supposed to reach her couldn't, then left at just the right time of year to be suffused with a lifetime of elemental air power that had been backed up.
*shrug* Yeah, she's basically a superhero.
Previously, the explanation for weakened flight was that Ob agents accidentally damaged the planar connection to Avilona by messing with the flying ziggurat 200 years ago -- before that flight worked in the world, afterwards the five minute limit appeared and all flying animals too big to fly without magic were grounded. The idea that Avilona is naturally hard on fliers doesn't make a whole lot of sense to me.
