Warden

The Warden is the Ardenian supervisor of the player in Building of the Hivemind. He tells the player of their task and watches you for the beginning segment of the game.

Gameplay
It has only been shown so far that Warden appears only at the beginning of the game, telling you to do your job and watching you closely as you collect items to be picked up by a Helicopter.

He will constantly look in your direction, even directly behind him, making him able to turn his head 360 degrees.

After you collect all of the items he hints at going into a specific building where a door just opened, which once you enter starts the actual game.
