he paused for longer than expected , plucked a wayward string or two , felt fatigue as it descended , ordered up a dwarven brew , sipped the tankard slow and steady , held it high above his head , and when the silence had descended , this is what he said : i find that i am growing weary ; my throat is rough and sore ; the calluses upon my fingers fall in flecks upon the floor ; ill sing but one or two more ballads ; short and simply set ; and then retire to my chambers so i can get some rest .
