It will of course be a PvP event. The GMA would be at a central location.
In escort the GMA you have to safely escort the GMA back to faction home base after finding him/her. You must approach the GMA and say "I am your escort" THE ESCORT CANNOT DIE! Otherwise GMA will turn around and go back to the central location and it can start again; make sure not to get GMA stuck on a rock or fence, or they will return to central location. It will be an hour long event. If neither faction succeeds no one wins.
In kill the GS you have to kill the enemy faction GS who will have increased rec/hp for the event. the first faction to take out the enemy GS WINS!
