Somewhat of a spoiler, I suppose. So, be warned.



The girl with the mask is Chrom's daughter, from about 15 (Or so?) years in the future. She, of course, time travels back in time to prevent some major bad crap from happening and dons the mask to hide her identity for some time. She and Chrom get into a fight at one point, and I assume it's possible for Chrom to die in it so...this.
