Angel-of-Imagination
"We can't ask questions, it's forbidden.
We can't leave the mansion's giant walls, it's impossible."
For who-knows-how-long, the Doll House had been their home. Everything was "normal" and "perfect". Nothing bad happens and no one gets hurt - as long as they don't question anything. Like that, everything was as usual as ever.
Until the hall ways appear empty,
until one of them had a nightmare,
until a being different from them showed up.
