Not bad, there's not much more to add besides details. The part about being sent back to your world and pulled back again is true, but there's the twist that sometimes you return here with no memories of having been here, even if you come from a later point in time. You may also end being pulled back here from an earlier time than before, again with no memories of being here.

On the power part, that only holds true so long as you remain on the enclosure, if you're out of the barrier your power is at normal, the wings remain though. And in case you weren't before, you're definitively mortal here even if it's only by getting the wings ripped off. Everyone returns after a week more or less though.

And from time to time it's possible that you will find yourself or those around you losing their minds, bodies and other "fun" stuff. Always temporal but annoying nonetheless.

[At least it's not as regular as it was before.]
