Hero's Call: Dustwallow Marsh!

Another way to get to Theramore is by picking up this quest in Booty Bay, Cape of Stranglethorn and take the boat to Ratchet. You will be offered a free flight trip to Theramore, without the usual requirement of having to know the destination flight path.
Especially handy if you've been questing in STV, rather than the Wetlands, and you don't have the fp to get close to Menethil Harbour.

I know this quest is shown in the series list at the top right as well, but I thought I should point out the difference between the two and why this one could be handier. :)

This quest cannot be picked up in Ironforge.

Apparently the Hero's Call quests parallel usually more profitable breadcrumb quests. If you accept/complete one you can't accept the other.

Before picking up a Hero's Call quest you might want to check to see if there is a breadcrumb quest available. The breadcrumbs generally offer much more exp, rep, and silver. This Hero's Call quest isn't that much different from the breadcrumb.
