Taking this idea a little further, my proposal for the Time of Unparalleled Darkness would have been for Azalin to cause a Grandfather Paradox, forcing the Demiplane to indefinitely alternate between two timelines. This could be made even worse if Azalin left clues to himself each time, so each iteration would collapse and reset a little earlier each time.Strahdsbuddy wrote:73. CHRONOMANCY!

Done correctly, the window of time between an iteration's start and an iteration's reset could become very small, maybe no more than a week. Adventurers who want to solve this have to make sure they don't overrun the final reset time limit or they will be trapped in the loop as well.
For added fun, have this occur during the Grand Conjunction, when Ravenloft briefly touched every other plane. This means that the entire multiverse will start recurring too, always resetting itself after the one week limit.
There is also a silly pun here about parallel universes and Time of Unparalleled Darkness.
