You arrive in a foreign town. The roads are sandy, and old western music plays as you swing open the door to the saloon. "Beer", you say, and the bartender quickly fills you a glass and slides it over. Before it can reach you, a hand - a something intercedes. You look closer, and it's a glove grasping your drink loosely. The glass is slowly eaten away by the liquid inside, and you realize the bartender tried to poison you. You stand, looking for the man who saved your life, but the seat is empty. You spot a dark figure by the door, a gloved hand resting atop the handle. "Wait!" you shout, and the figure startles. The glove falls, revealing a hoof. You look closer under the hood, but there is no human face there - merely the elongated muzzle of a horse. Still, you think, you owe this horse your life. "You saved me," you say. "How can I thank you?" "When you reach your final destination," says the horse in a deep baritone, "Look the devil in the eyes, and tell him Juan sent you."
