Role reversal! Au, In this au, Lissa does not know that she is the daughter of the exael(how the heck do you spell this) as her father hide her birth from the kingdom, she was raised to be the a perfect guard to protect Emmeryn who also didn't know that Lissa was her sister. Their mother, in fear of more of her children getting manipulated by her "loving" husband, takes the child that she knew that he wouldn't manipulate, Chrom was taken away as a toddler, away from Ylisse. 1/2
Chrom's mother take him to the very border of Ylisse, she teaches all she knows to him and even gifts him a beautiful white cloak. But they were found out and Chrom's mother defends her child dying in the process and tells him to go to plegia, to seek out help from Prince Reflect, Princess Robin and Queen Aversa, children of the late king of plegia, Validar. Yes, Reflect in this is youngest and is training to be a dark flier, this Reflect is more lay back than his sisters.
