Loch Modan Quests

Thought I'd document what I did, hope it's helpful. I did seven over what was needed for this achievement. Edited to add that I picked up lots of Ironforge rep and a bit of Gnomregan too.

Couldn't pick up Hero's Call: Loch Modan! too high level for it, so I started at South Gate Outpost. But there is another breadcrumb quest I missed called Reinforcements for Loch Modan that you can pick up in the High Seat of Ironforge.

As of 7.3.5 this is now separated into 4 story lines. 3 of them are self-evident, but the Road to Thelsamar requires you to finish the quests leading here from the pilot on the west end of Dun Morogh and then the spider killing quest that is linked to in the main box above.

I assume that the separation is to ensure no one gets the achievement without digging around WoWhead and extending the "content" time by a few worthless nuggets of time between cradle and grave.

The corresponding Horde achievement is Ghostlands Quests.

By completing one of these achievements, the other one will automatically be achieved.
