Omega

The world was created by three gods:

Alpha created the sky and weather

Gamma created the water and all the sea creatures 

Omega created the earth, plants, creatures

Your character was born in the past where they help their father and his business partner, Aya McCloud, find the staff which belongs to the God Omega. You find it and she betrays you and your father by killing you both. You were holding the staff when you died.

You wake up a 1000 years later and now there is a city where you died, the city of Starburn. You met a guy name George who helped Ryan McCloud, a descendant of Aya, create a paramilitary organization called Gauntlet which got rid of virtually all crime in Starburn. Gauntlet controls the city it is the police force and they use whatever means necessary to stop crime and being peace to Starburn. George is a whistleblower and now Gauntlet is hunting him now. 

You end up stealing the staff from Starburn Museum which causes Gauntlet to lock the city down.  You find out that the McCloud family is basically royalty in this world and since you can’t get revenge from Aya(since she is long dead) you decide to take it out on her descendants starting with Ryan. You will have to fight through Gauntlet and reopen the city first.
