Do you have a WoG on that? Or just making a statement of confidence? Because it started off as there being no "obvious" solutions, when this seems pretty obvious. I'm pretty sure I was thinking it even when I first read the update, and I was half-asleep then.
Sure, if we were doing some really complex, or out of the blue thing, but... I don't know, maybe it's just different perspectives that makes this seem so extremely simple. Chaos steals power from Waystones to power dimensional shift, so we just... turn off the power.
