Found a door. But I dont jave PI :( Do the skull quest on venus. At the very back where the queens bounty for a servitor use to be at, is a new path. But it is blocked by a vex barrier. Look back to where you entered the area. On the otherside of the wall there was a walkway. There was a portion of the wall with the same active field. I believe that is the true door, if you have the key.
