I think the stranger is from the future

I think this because when u get the strangers rifle the descriptionsays some parts are not exist or from the future. Then I relize from the Venus mission the strangers call she acts like she knows a whole lot about the vex. Next I think she is a survivor of the Vex taking earth and want through a Vex Gate that made her go in the past then she try's to stop it or slow it down the event by a gruaderian. That's you. She takes you the Awoken so you can destroy the black garden and kill the Vex. This is my thoery about the stranger
