Stories? Seriously, most seasonal "stories" are just standalone crap that doesn't even advance the Destiny saga. Two things have happened that matter. Eris became a hive God just long enough to lock that whiny Knight God out of her throne world so that we will be able to kill her. This also implies that we are diverging from the past "futures" in which we lost because Eris turned to darkness. And the current season... The Ahamkara has wished us a way into the Traveler so we can try to track down the last hive God and The Witness in the upcoming DLC. Everything else has been "the enemy of my enemy is my friend" nonsense that the current generation of shallow young adults seems to believe is so deeply moral.
