It is obvious that the Red Mage is not telling us everything, and the Black Mask we've found is a clue that her 'war' could be a much bigger thing than it might look at first. And it is dangerous to immerse yourself into a dark plot blindly. Finding out the story behind the Mask might at least allow us to understand the whole game better, and be able to turn back before any major disaster strikes. Hmm, didn't we already hear about masked mages somewhere...?
