After completing the achievement, Welcome to Draenor, your ship takes you to the shores of Shadowmoon Valley. Speak to [npc=79206] at coords 27.0, 8.1, and accept the quest, Finding a Foothold.
1. Finding a Foothold - (Video) - Travel south, up the hilly path (path starts @ 27.4, 12.9) into Lunarfall.
• Follow it uphill to [npc=79470] at coords 28.8, 16.2, and turn in the quest Finding a Foothold. Next, accept the quest, For the Alliance!.
2. For the Alliance! - (Video) - Click on the Alliance Banner (in front of you) located at coords 29.0, 16.1.
• After [npc=79242] will open a portal to bring [npc=79243] from Stormwind. Speak to [npc=79243] (at coords 29.1, 16.2) and turn in the quest For the Alliance!, accepting next Ravenous Ravens and Looking for Lumber.
3. Looking for Lumber - (Video) - Click on the [object=230335], throughout this area of Lunarfall, to mark 8 the trees for cutting (they appear as white flags).
• The flags should be fairly obvious, but the coords that I found the flags were:
28.6, 17.2
29.1, 17.8
29.3, 19.2
29.0, 19.8
29.1, 20.1
29.6, 20.3
29.7, 19.6
29.9, 18.8
• Ravenous Ravens - While completing the [object=230335], kill 6 [npc=82037] that get in your way. In all likelihood, you will end up killing a few extra [npc=82037] while you are completing the [object=230335].
• Go north to coords 29.1, 16.2, and turn in both quests to [npc=79243].
• Accept the quest Quakefist from [npc=79567] at coords 28.9, 16.4.
4. Quakefist - (Video) - Travel south and go inside the tree (entrance @ coords 29.9, 20.9), and kill [npc=81360].
• Leave the tree, and travel north to coords 28.9, 16.4 and turn the quest in at [npc=79567].
