A Worthy Weapon

Of all the times to have such rotten luck!$B$BMy tournament blade has gone missing and I need it for a match this afternoon.$B$BOne of the bards tells me that travelers used to present winter hyacinths to a lonely maiden in return for gifts. Those hyacinths grow only on the ice flowing from the Ironwall Dam, on Crystalsong Forest's northwestern border with Icecrown. Gather the flowers and take them to Drak'Mar lake in northeastern Dragonblight, near its border with Zul'Drak and Grizzly Hills.
