Back in my Fire Emblem Heroes Era (my FEH-ra) I thought a whole lot about what it would be like if my characters were units in that game. So naturally I picked up my tablet, made neutral, damaged, attack, and special attack portraits for Vae, gave her stats and abilities, and put her in front of the UI.
I remember I tried to make her pretty balanced with the other units in the game. Like, I made her really strong, of course, but no stronger than the other high-tier units that were in the game at the time. She has a unique weapon and a unique A-Passive, and I DID write down what those would do at some point, but I can't find where I wrote that down. So who knows what those were supposed to be.
