Ok hear me out Maybe when hard mode drops instead of getting the exotic weapon (Like Mythoclast RIP) you have a chance of getting an exotic ghost that will guide you to weapon parts and mini boss encounters.Maybe it'll allow you to activate a 4th CoO boss and maybe a quest or mission.It'll be an exotic quest but it can't be that short.It'd take a few professionals at bungie to figure it out but have it revolve around a character.If it were to happen it'd most likely be Banshee and Eris but i'd make all the vanguard leaders (Zavala Ikora Cayde) and maybe some of the other faction leaders get in on the action.Maybe even Rahool.If Rahool were to be involved it'd involve some background on the Cryptarchs (Old and new) Kind of like the missions where you get your new subclasses you'd be able to go to certain places and find pieces of info on the weapon (with the help of Eris of course) and -blam!- it! Bring in some background on Eriana and let all that build up into a big finale where the player has to face a boss, something named Protector of the Heart where you kill him and are able to take the ghost and summon the heart of Oryx while you fight off enemies with the help of PLOT TWIST the vex.If you remember the mission Regicide where the vex were standing still and not shooting, if you didn't shoot them your ghost will reprogram them to help you.If you shot (They were defenseless HOW DARE YOU!) you're on your own.At the end your screen goes white due to light like when traveling into the black garden and there is a portal.You step into it and it takes you to the Dreadnaught where the exotic gun is sitting there for your taking.
