Edit (11/23/11): Charcoal on printer paper a friend of mine drew up of the Marchave clan--that sigil etched into A'ha's brow at the moment of his first kill of a xenomorph. I changed teh image and thumbnail in favor of a cleaned-up, more even shading and improved shape version. Its meaning is essentially 'ambition,' signified by the claw over the dark moon, or to reach for a great goal. Also, "Marru-shah-veh." Phoenetics are your friends.
