Marick is operating under the disguise of an alias known as "Ghost." By wearing a full mask and nondescript robe and weapons, the masquerade is enhanced by Marick's ability to use Faceless II to change his eye and hair color. His training in Subterfuge also allows him to not telegraph his typical movements or mannerisms to give himself away as Marick Arconae.

Ghost appears to have a will of Iron. He is able to shrug off all but the strongest of mental-assaults, and seems to be immune to taunts. His confidence in this aspect leads him to act without fear, and even the strongest of metals can be broken under the right circumstances. And the stronger a will is, the harder it hits if it does break.

While the Clan believes he is offworld on diplomacy, he has in fact remained behind to witness events that would happen in his absence. He keeps his identity hidden behind a careful disguise, and has sided with the Arconae-supporting separatists against the Quaestors. Marick still retains all of his usual skills, but committed himself to learning how to better hide his signature in the Force through Concealment. He is very careful to not reveal himself to anyone, lest the illusion of his absence be ruined.

Ghost does not speak. He only acts. If he does speak, he uses monosyllabic questions or commands that come out modulated thanks to the mask and Marick's Subterfuge skills.

An Obelisk to his core, Marick views the Force as a tool, not a crutch. He has spent years honing his body into the perfect weapon: reflexes wired to hair-triggers that give him a freakish athleticism and grace. Instead of using the Force as a weapon against others, Marick has become adept at not just pushing his body past its normal limits with Amplification, but timing precisely when to use it so as to never burn out. While this training makes Marick deadly in close quarters--with or without the Force--it leaves him vulnerable to ranged fighters and marksman.

Marick glides through combat like a windblown leaf: always spinning and in motion while adapting to his surroundings. Every twist or turn of his body is executed with kinetic purpose, his attacks quick and precise like the fangs of a serpent. He will confuse opponents by seamlessly alternating his sword-hand and prefers to leave one hand free at all times for improvisation. He will only wield both sabers in tandem when forced into confronting a heavy concentration of opponents. In those situations, or when forced into tight quarters, Marick has to rely on more conservative and less dynamic tactics that make him easier to telegraph.
