you suddenly woke up in the lost ruins of a city you wouldn't able to remember.. Anywhere is rubble, windows broken, broken roof, torn down walls of your 'unknown house' you are quite weak, your legs hurt from the debris it lays upon it.. Its raining.. You stood up and went to the bathroom.. You look at yourself.. As you said

"Who are you?"

A hint for the start for your life through the abundance of this world.. You aren't alone..
