Antler

 is the name given to the brahmin skull that a cult of nightkin worship, found in the basement level of the REPCONN Test Site.

Origin
Antler is a brahmin skull that Davison, a former Captain in the Master's Super Mutant Army, picked up while he and his troop of nightkin wandered the Wasteland. Nightkin develop a form of schizophrenia from prolonged Stealth Boy use; because of this, they believe that the skull gives them orders and guidance.

Davison relates that his troops were suffering mentally from being separated from Master, and that since finding Antler to worship "everything's been going really well." Incidentally, Antler acts as a conduit for higher-tier planning that Davison would otherwise abandon in favor of brute force.

It's Antler's suggestion (in Davison's mind) that the Courier help with the ghoul holed up in the room containing the stealth boy information, and it's Antler's confirmation of the Courier's discovery (that the Stealth Boy shipment was not at the REPCONN facility) that convinces Davison that the Courier is telling the truth.

Antler is housed in the REPCONN Test Site basement, where he is guarded by Davison.

Bugs

 * After killing Davison, you may freely move Antler around. Although when Antler is placed on the floor, it may turn invisible, only turning visible again by being moved around.
 * Occasionally, Davison may attack even if Antler is moved in any other way than the players interaction. This may be caused by a bug or by a companion that accidentally comes in contact with Antler.

Appearances
appears only in Fallout: New Vegas.
