Muz's left forearm was lost in combat, replaced by a synthetic limb of his own making. The tritanium limb is moderately armoured and serves a variety of other functions. Among these is an encrypted commlink-enabled datapad with control pad for his ship, the Fallen Spear. The arm has electromagnetic plates in the palm of the hand, which when activated, has the strength to secure 50 Kg. There is also a recessed coded disconnect which allows Muz to detach the arm from the socket rather quickly. The arm is also hermetically sealed, to protect the inner workings from environmental factors.
