You find 19 year old Shanna Dorland sitting at a Cafe. You decide to check in on her. She look down at her coffee, no longer steaming. Likely a testament to how long she's been waiting...

Hello, I'm Catria. Who might you be?

Hello there, it's me, Palla. I'm officially in the Whitewings.

The 3 sisters (Juno age 27, Thea age 24, ans Shanna age 21) are sitting in their dorm room, and they gain a new roommate. You! You're all in Professor Byleth's class. (Far left is Thea, middle is Shanna, Juno on the right)

She escaped from the fictional country called Dawncross, and now your roommate.
