Brogg is relishes the thought of taking his revenge on the black dragonkin of the marsh. <name>, you have been very helpful in preparing for this moment. Will you help?
Take Brogg's clan banner and travel east until you see a cave like a dragon's mouth. At the entrance to that cave, plant and issue Brogg's challenge to Onyxia.
Brogg and Stonemaul will have their lands back!
Brogg will have his revenge!
<Brogg listens as you recount your experience at the entrance to Onyxia's Lair>
Brogg suspected Onyxia would be too much of a coward to confront you. Just like black dragonflight to attack when victory guaranteed.
Brogg is grateful for your help, <name>, and he will never forget what you have done for him. Brogg will never give up his quest to bring Stonemaul back where they belong.
Stand directly in front of the entrance to Onyxia's Lair when you plant the . A level 41 drake (Smolderwing) will spawn and fly out from the cave, you must defeat it to get quest credit. Note that you need to be outside the cave. If the text above your mini map reads "Onyxia's Lair" you are too far inside.
As of 12/15/07 the quest is bugged so that if someone starts the quest but does not kill Smolderwing no one else will be able to summon him unless a GM despawns him.
