There's a door at the end of the hall that's covered in pearls and gold. The singing's coming from there, but it's abruptly cut off and you hear a scream that's also quickly cut off. There's two guards outside the door.
There's four guards in the room too, each in a different corner. They draw their spears when they see you. Kira's sitting on her bed, curled up into a ball. She has a black eye.
