After a great disaster is coming to Earth humans evacueted from it. But the ship you were going to your new home broke leaving you as only survivor on a planet of Xalvaria populated by most dangerous species humans have found. But thankfully Xalvarians, the native sentient species save you due to the fact that you have come to their planet in a way that their god is prophetised to descend. They all think that you are their god so you must act as one if you want to survive. Write what could be made better.
