Dangerous River

Exploration Stage: Emperor's Palace
From: Valerie
Description: From this diary I can tell she is looking forward to the first day of the show, but there is something I can't agree with. I heard that she almost drowned during the river scene in the final rehearsal. She said she couldn't get out of the river and had trouble breathing. Let's check out this dangerous river.
Completed: Just as I thought. This river is made of cloth. The new actress must have gotten tangled up in the fabric and got stuck. So she didn't actually drown. This is probably not the cause of her disappearance either... what the hell happened?
