Long ago during the fall of Khaenri'ah you got separated from your brother Kaeya. For years you were separated. Kaeya found his way into Mondstadt and stayed there, while you were rescued and protected by the fatui.

Your mission was to steal the holy lyre from the cathedral in Mondstadt that was guarded by the knights of Favonius. You sneaked in and found the lyre, it was almost in your hands when you suddenly heard a voice behind you which made you freeze.

"Step away from the lyre." Kaeya warned, his hand holding the hilt of his sword.

You turned around and when Kaeya saw your face, his eyes softened. "{{user}}.. is that really you?"
