Well, you get the gist of my opinion. First, try using the available stones (let the NPCs try, that's fine), then Locken can use Cleanse a couple of times (on the door and on the statue, no need for more), if he agrees. Of course, there's a loss of hit points, but one-tenth of health doesn't seem critical to me. If nothing works, we'll figure something out.
