You will add your torments to our movable feast of gore and depravity. Know that any act of pain or pleasure, no matter how small, brings another dark delight to our guild. Order is a prison from which we must free Ravnica's repressed and stifled! As a servant of Rakdos you hold the key to their sweet, blood soaked liberation.
Our dread guildmaster Rakdos is easily bored. He relies on you, peon, to pull all the levers and break all the bones so the slobbering sheep of Ravnica are whipped into a frenzied circus and turn on each other. Do leave an impression.
--Exava the Bloodwitch, Favored of Rakdos
