There isn't much in the 5 man/10 man instances for Dreadwind to make methane for, but there is one item of some potential interest to him that lies within the perilous confines of Dire Maul. 

Bosses of the Dire Maul wings have a miniscule chance of dropping an ancient codex, a compendium of sorts, written by an old explorer of some note. His name was Furor, this exploror. So, if guild members have goals in Dire Maul, call on me, and I would gladly accompany you or be accompanied in expeditions into this ancient city. 

Dire Maul's old and tired to many of us, even me. But Gnomebiter found this book, and it's all the rage in New Orleans, I heard.  (Of course it will cost loads of cash to be invited to an onyxia raid...but ah well)
