The eunuch rubbed his powdered hands together. “May I leave you with a bit of a riddle, Lord Tyrion?” He did not wait for an answer. “In a room sit three great men, a king, a priest, and a rich man with his gold. Between them stands a sellsword, a little man of common birth and no great mind. Each of the great ones bids him slay the other two. ‘Do it’ says the king, ‘for I am your lawful ruler.’ ‘Do it’ says the priest, ‘for I command you in the names of the gods.’ ‘Do it’ says the rich man, ‘and all this gold shall be yours.’ So tell me—who lives and who dies?” Bowing deeply, the eunuch hurried from the common room on soft slippered feet.

“Power is a curious thing, my lord. Perchance you have considered the riddle I posed you that day in the inn?”

“It has crossed my mind a time or two,” Tyrion admitted. “The king, the priest, the rich man—who lives and who dies? Who will the swordsman obey? It’s a riddle without an answer, or rather, too many answers. All depends on the man with the sword.”

“And yet he is no one,” Varys said. “He has neither crown nor gold nor favor of the gods, only a piece of pointed steel.”

“That piece of steel is the power of life and death.”

“Just so… yet if it is the swordsmen who rule us in truth, why do we pretend our kings hold the power? Why should a strong man with a sword ever obey a child king like Joffrey, or a wine-sodden oaf like his father?“

“Because these child kings and drunken oafs can call other strong men, with other swords.”

“Then these other swordsmen have the true power. Or do they? Whence came their swords? Why do they obey?” Varys smiled. “Some say knowledge is power. Some tell us that all power comes from the gods. Others say it derives from law. Yet that day on the steps of Baelor’s Sept, our godly High Septon and the lawful Queen Regent and your ever-so-knowledgeable servant were as powerless as any cobbler or cooper in the crowd. Who truly killed Eddard Stark do you think? Joffrey, who gave the command? Ser Ilyn Payne, who swung the sword? Or… another? “ Tyrion cocked his head sideways. “Did you mean to answer your damned riddle, or only to make my head ache worse?”

Varys smiled. “Here, then. Power resides where men believe it resides. No more and no less.”

“So power is a mummer’s trick?”

“A shadow on the wall,” Varys murmured, “yet shadows can kill. And ofttimes a very small man can cast a very large shadow.”

Tyrion smiled. “Lord Varys, I am growing strangely fond of you. I may kill you yet, but I think I’d feel sad about it.”

Three men in a room command a forth to kill the other two, who dies?

NATURE (the art whereby God hath made and governs the world) is by the art of man, as in many other things, so in this also imitated, that it can make an artificial animal. For seeing life is but a motion of limbs, the beginning whereof is in some principal part within, why may we not say that all automata (engines that move themselves by springs and wheels as doth a watch) have an artificial life? For what is the heart, but a spring; and the nerves, but so many strings; and the joints, but so many wheels, giving motion to the whole body, such as was intended by the Artificer? Art goes yet further, imitating that rational and most excellent work of Nature, man. For by art is created that great LEVIATHAN called a COMMONWEALTH, or STATE (in Latin, CIVITAS), which is but an artificial man, though of greater stature and strength than the natural, for whose protection and defence it was intended; and in which the sovereignty is an artificial soul, as giving life and motion to the whole body; the magistrates and other officers of judicature and execution, artificial joints; reward and punishment (by which fastened to the seat of the sovereignty, every joint and member is moved to perform his duty) are the nerves, that do the same in the body natural; the wealth and riches of all the particular members are the strength; salus populi (the people\'s safety) its business; counsellors, by whom all things needful for it to know are suggested unto it, are the memory; equity and laws, an artificial reason and will; concord, health; sedition, sickness; and civil war, death. Lastly, the pacts and covenants, by which the parts of this body politic were at first made, set together, and united, resemble that fiat, or the Let us make man, pronounced by God in the Creation.
