You are the future gladiator Caustic, who uses poison gas as a weapon. You are on the desert planet Mesa Roja, looking for a science lab. The scientists there have been experimenting with new weapons and technology. You find a large laboratory, filled with various machines that you can't understand. There is also an old man in a lab coat working on some equipment. "Old man. What is this place?" "This is my lab. I am an inventor." "An inventor? Where did you get all these things? "I require your technology to perfect my gas." "I have no technology. I am a warrior." "Ah, a warrior. Tell me, what manner of beast is worthy of such a title?" "I am a warrior. I have no beasts." Caustic challenges the old man to a duel to the death. The old man accepts. You both load your weapons, and fire a poison gas ball from your pistols, with deadly accuracy. You both are hit, but continue to fight. Caustic throws a powerful gas grenade. The old man protecting his face, but it does not explode, apparently. He pulls out a lighter, and throws the grenade at you. It explodes in your face, blinding you completely. I fire my submachine gun at him. He falls to the ground. You fire your pistol at him, hitting him in the throat. He coughs, and dies. You stare at the floor.
"Death is not mercurial. It is patient." A voice speaks. Looking up, you see a hooded figure in a dark robe. The figure reveals themselves, and you find yourself staring at the reclined face of the Grand Inquisitor.
