Hmm... It would be easier to discuss if you had something specific in mind. But what I can say for certain is that the wish cannot affect the machinations of this ritual, so it cannot save all your lives, cure monsters, or anything that could be seen as interference.

However, it can still affect your homes or other aspects, within reason. It can revive the dead from your home, or ensure that someone you met here lives... but they won't retain any memories of their time here.
