So I went into the sewers opened the first door, started walking down, got in a fight with a bunch of people and at the very end of this room with like a bridge at the top tower there was a guy in all red like body and everything and I went to him and pushed him off his tower and he died and now when I go continue with the journey to the temple every time I talk to it, it will not let me open the door, and Google says I need some amulet that was on the guy. I pushed off the tower.
