You know what? I realize now that you altered "Find a Cure" into "A Cure For All". I'm scratching my head how to tell you something without giving any campaign spoilers. Allow me to communicate with you in this hider to at least protect anyone else reading through from having something ruined for them...

[hider=Potential spoiler]
A cure-all is actually impossible in this game per the rules. I think that must be why they didn't suggest it as a potential quest line. However, if you like the idea of learning something valuable that could save a ton of people's lives, might I direct you toward the "Blighted Landscape" quest line?
