No...you go through the dormant portal where the jumping puzzle is. It teleports you into the venus portal gate from vog. You slay the vex juggernaut inside and a triangular doorway opens up. You receive a paraedyths grimoire and loot the 6th chest. Inside the chest you get some goodies but also "paraedyths ghost shell" a relic from the past. You take it to the FWC lady and proceed with the sleeper simulant quest. Period. End of story.
