Skull-Taker is a Great sword that is traditionally carried by the Sargent of the squad carried by the Chimera Alpha-Seeker. The sword is stored in a set of hooks mounted just under the hole for the turret that the Sargent operates when they are in Alpha-Seeker. Upon disembarkation Skull-Taker is slung over the Sargent's shoulder and carried across their back.
Skull-Taker is only used in single combat against enemy commanders or in execution of captured commanders. After their head is taken, a kill marker is added to the blade at the end of the row of tallies and hatch marks. A full half of the blade has been covered in the long life of Skull-Taker.
