Heck yeah, these sort of things are really great! I recommend pages like this you mark as ‘gm only’, that way only you (and a co-gm, if you have one) can see them, and the players are left wondering what’s coming.
Ascendant campaigns can view previous versions of their pages, see what has changed (and who did it), and even restore old versions. It's like having a rewind button for your campaign.
We've already been saving your edits, so if you
you will have instant access to your previous versions. Plus, you get a 15-day free trial, so there's nothing to lose.
