I was playing patrol on the cosmodrome with a friend yesterday, and we stumbled upon "The Eyes, The Hand, and The Heart of Crota". We looked it up and realized the purpose of them being there, but we also found something else. Maybe it's part of a mission or I'm just crazy, but where The Heart of Crota is located, he is praying to a door, a door to a hive ship or beacon of some kind; and on the door you can see three glyphs of some kind. I've also noticed two other ships or beacons just like it, around the cosmodrome, located in Skywatch and Kingswatch, and somehow We caused these ships/beacons to glow much more green than usual, however we only found two. My mind is dead set on thinking that there is something to be done here, but I don't know what it is. Maybe killing all of Crota servants at the same time or in a certain order, or maybe all of this is a quest line. I don't know. Let me know if I'm on to something haha
