While there are many encounters, you only need to go through all 11 of them once in the span of of week, then you unlock the individual raids, which you can do separately (I.E. you could go into King's Fall without needing to do Crota's End first.) And once unlocked they are unlocked forever, no need to go back into the Osmium Court raid unless you want a chance at getting the Exotic Relic mentioned in the post (assuming everything were to added from this post into the game). Lore wise on why Oryx's Shade would be immune? No clue. Maybe send a chain of taken goblins with him extending through the Rupture so that they just keep the one in front of them immune until the last one shields the shade. But in all seriousness, we were just trying to come up with something to bridge the two raids and with how quickly we came up with all this, it wasn't half bad but perfect by no means. If Bungie were to add all this I'd expect them to create a much better lore friendly linkage than we did.
