This is a little theory I have been dwelling over the last couple weeks. I'll do it in bullet points to speed things up: Saladin speaks of a Shadow that will swallow the sun A scannable on Nessus speaks of an object on the other side of the sun On Io there are drawings of a large dark sphere next to an orange sphere Now here's the science bit! The next dlc is about Osiris and Osiris got too close to the vex. Quaria blade transform lost it's battle with the hive in the ascendanct realm after not ingesting a worm. Quaria became taken A BIG DARK SPHERE OF TAKEN BLIGHT, dum dum duuumm There MAYBE a worm on titan as we have seen under water Quaria is coming to take the worm! We're dooooooomed!
