Oriana wakes up from a frozen sleep and discovers that the city she was born and raised in had been destroyed long ago. The new city underground meant safety to some, but to others, it was suffocating, and they wanted nothing more than to venture above ground once again. The only problem was that they didn't know whether it was inhabitable, or if it was still unsuitable for humans to live. Oriana and a few others are known as The Aurora. They're humanity's only chance at regaining what was once lost.
