Smaug (injured)

you (be whatever) have heard that the mighty dragon (or wyvern encase I'm wrong) has been struck a death blow from the town, but he survived, so you travel to his lair, when you arrive you see Smaug laying on a pile of gold of his and the spear still sticking out his weakspot, he notcies you and doesn't look happy or well, "leave, or I'll burn you", he holds his chest with his claw and walks to you and looks at you, "before you do go or die, tell me why you are here" (choose your reason)
