And a story has significant parts then.
What's worse, is that they take up some time. One needs to time things right.
Not quite so bad as a pregnancy. I can, after all, shift the time at which things occur. If they end up walking out under a blue sky, it would work as long as it's still early enough to avoid much notice.
hmmm. . .
Perhaps they could use a time stop rather than a sleep spell to prepare for the escape. Though I would have to settle how that would affect the curse that forces a character into animal form for certain amounts of time. . . eh, probably his subjective, because otherwise the loophole is too blatant, even if time stop is a big spell. . . and I remember the Celestial Clock I had thrown in earlier. . . .
Still need to watch the sunrise and do some timing. The spell can't go off at once. 0:)
