So I just played through the Paradox daily story mission, and while browsing around the internet searching for some stuff about Praedyth I happened upon a youtube video about some hidden Ghosts around that mission. [url=https://www.youtube.com/watch?v=JfWI3l1xTlI]This is it here.[/url] I found all the Ghosts and beat the big encounter at the end. I noticed that when I defeated the Blighted Mind (what would normally be considered the end of that mission.) Praedyth said something about a door closing and excitedly declared that he was going to make it out of the Vault. In some other points of the mission, Praedyth addressed my character personally. This all got me thinking, could there be an Expansion further down the line centred around Praedyth causing a paradox and appearing in the Tower? Unable to fully interact with the world he fills in a kind of Crota's Bane role but with missions based around the Vault and the Vex. I'm not a great artists but I have an image in my head of Praedyth as a very smartly-dressed Warlock surrounded by books and dismantled Vex parts, occasionally flickering in and out of view with the same kind of tv-static-glitch effect the Vex use when teleporting.
