Many decades have passed since the Dragon Smaug's appetite and lust for gold led him south from the Withered Heath to assail the kingdom of the Dwarves. Swift and terrible was his coming, in which untold multitudes of men and Dwarves died in fire and ruin. For now, all is peaceful in the halls of the sleeping Dragon, coiled serpent-like in his hoard.
Yet this stillness is an illusion, for the jealous mind of a Dragon is never restful. Fevered dreams of thieves and usurpers make his slumber an angry one, eyes snapping open to dart back and forth, long snake-neck rising suddenly to swing about, counting the coins and cups, platters and gem-studded jewellery, his senses keenly tuned to the barest hint of scent or soft step that might herald the intrusion of some greedy, reckless fool. Smaug will share no trinket of his hoard, and as immeasurably vast and powerful as he is, doubt gnaws the corners of his confidence, fraying his wits and dooming him to a restless, broken, red-hot sleep.
Into this simmering pit of suspicion and rage stumbles a simple hobbit with no thought of treasure. Propelled by his obligation to honour a naive promise to a friend and prove himself worthy of a Wizard's faith, Bilbo Baggins treads nervously upon the hallowed gold. It is a simple act of astounding bravery that impels each nervous step, spilling trickles of coins that become a cascade, a landslide of gold that will in turn unleash upon the world a monstrous wrath, change the course of history and precipitate a brief and bloody siege: for Bilbo has awoken the Dragon.
