Before you laugh, hear me out. Last night as I was turning in the Queen's Wrath bounties, I noticed there are five giant signs in between the pillars, on the wall, above Petra.(when running up to her from spawn point) These five signs/patterns seem to be a code or a clue to something. If you run around in the reef, you will see the same five patterns in random locations. The pattern is a "U" with what could be a direction of which way to look or move or something. So I started messing around with the "baby servitor ball" and moved it to these locations. I tried taking the light that the Servitor shines in the same directions as what the Pattern looks but I wasn't sure what else to do. I then noticed that four out of the five signs were lit up. I gave up after an hour of screwing around and seeing if it has to do anything with that Emissary guarding the door but nothing happen. BUT, when I left for orbit, I got this noise like I unlocked something or something was entered. It was strange and I think those five signs have a meaning and not a random decoration on the wall. These signs are on some barrels as well and I think they are a part of The House of Judgement or another fallen House. I really think I am on to something tho. There's got to be a reason why that emissary stands guard in front of that door. I hope it is not a part of TTK expansion. Does anyone have any suggestions or seen the signs on the wall that I am talking about? Discuss.
