Find Lord Incendius in Blackrock Depths and destroy him!
Are you sure Pyron said 'Incendius' when he died?
<Jalinda swallows hard.>
Lord Incendius is purported to be a minion of Ragnaros! Oh dear, oh dear... whatever will we do?
Do you think you can handle another mission? I don't have anybody else to send, <name>!
We will never get a team in if Incendius continues to raise Pyron from the ashes.
You'll have to find and destroy Lord Incendius!
