Well...going from Praedyth's dialogue in the alternate ending of Paradox... The Stranger is the 1 and only constant in every single timeline there is. She is 100% involved with the Vex and seems to freely travel time. Right now she and whomever is teamed with her are probably fighting multiple battles in who knows how many timelines. She seems to want to help us survive though. She seems to have intel and knowledge nessicary for us to defeat the Vex atleast. Praedyth & the Vex seem to be both frightened of her as yet resent her. I want to see her return desperately. I want her to have her own stand alone videogame. Honestly...the idea of playing a solo game starring her is intoxicating. She her storyline/events/team are 100% more interesting than the characters we currently deal with.
