Dark Guardian- The Vanguard has found something unusual on one of the Guardians head cams and see something drastic. They send you alone or with others to investigate this new discovery. You have to travel to the Awoken to see if they know this new threat. They will deny what they hear of the new threat. They will say that the cam that you showed came from the moon Titan of Jupiter by the makings it had in the background. The Vanguard now sends you on a strike on the moon Titan. You will find an army of Vex which have been crushed and into pieces. You will even find a dead Gate Lord. In the distance you will see a last stand point from a fellow Guardian. But you will not find his body anywhere. You go down deeper in this ancient temple built be the Vex. You fight Vex when getting lower into the temple. But soon you stop to the same place the head came showed. You'll go through the door and find who did all of this. A Dark Guardian. He will fight you and your strike mates. You will defeats him but not killing him. You will travel back to the tower. While you are there they could not find what I happening. But a Warlock says that he has been exposed to the Darkness. The Speaker found by an ancient Vex manuscript that you can not kill these kinds of Guardian that they are immortal. They will send you back to Titan and find more of what is happening. The Speaker calls through saying there has been more of the Dark Guardians that have been captured. You travel more fighting more Vex. You fight until there are no more. The Stranger comes back an gives you a warning of what these things can do. She's been fighting them for forever. That is why she left you on Venues. She gives you a ghost. She says that this ghost will be able to unlock more of the secrets of ancient Vex so you can figure out how to stop them. She then leaves you in the depths of the temple. You now contact the speaker of your new discovery and what it could do. He then tells you to go and search for a beacon that wasn't to far from you. When you finally get there you can see some pitch black fog that is passing by. You get anxious and try to leave, but you were too late. The black fog over came you. You get knocked out by a hit on the back of your head. You wake up before a vex ritual. You are tied up in rope making it impossible to escape. Then the vex ritual was done. Your mind is now twisted and your skin and armor is black. They turned you into a Dark Guardian. Your communications isn't functional such as your ghost. In this time the speaker sent teams of guardians to get you. Also the speaker got new info about the Dark Guardians, a way to stop them. Plasma is the only way to eliminate these new breed of evil. Before they get to you, you start to run (don't have weapons) while the vex are helping you get away. You don't know they have the plasma till they start shooting and a bullet hit your arm. You get to your ship with your dysfunctional ghost. You get away but you have nowhere to go. Your communicator starts to beep showing a map by an unknown person. You travel to the coordinates which happens to be on Mercury. There you will find some more Dark ones. Which fixes your ghost and implants some data to help you. You all start talking of a plan to defeat some guardians that will get in your way of destroying the traveler. Cayde-6, Commander Zavala, Ikora Ray. They themselves are coming to look for you on Mercury since they are the best. When they get there an army of vex are waiting for them, which took them a couple minuets. They bust through your door, a fight breaks loose. You finally capture them at a risk of two of your Dark teammates. Your Captain was going to kill them to finish your plan but you said wait. You said to keep them alive to give you answer. They thought it was a good idea. When you are keeping first watch on your prisoners Cayde-6 says," Hey you, let us out. If we are gone long enough the tower will send all of their guardians after you." In this act he had escaped his rope stabbing you in the arm with a plasma knife. Options- For PvP the teams won't be Alfa team or Bravo team. It could be light and dark witch would be more realistic for the game than killing other light full Guardians. This is what I have so far. Please comment saying what should happen next or what to change. Let's make this happen in a DLC. How do you know?
