My post starts out where Xavier died in my previous fight. Kind of just a continuation in the story X amount of time after the fight.

 A town lumberjack will come along and see the nasty mess that was left after the fight and start to explore. Sees the black lake and Gets poisoned and goes back to town.  The exact details will be in my post.

I can have the Mutated animals, the Diseased, attack around that same time after following him home. Its all just kind of a justification for your character to be concerned. On that note I don't care how heroic you want her to be. Just enough to want to force him to stop is fine with me. I can work with a lot or a little on the fly.

That sounds even better actually. A low level fight followed by a high level fight. It will make for a better story that's for sure. It would also make sense that Xaviers powers would have a negative effect in some way so that works for me.
