Starting out: To begin, you must have a riding skill of 300 and a flying mount (flight form doesn't seem to count, at least in the public test realm, sorry druids). If your character doesn’t have these necessary FFXIV Gold items, you must to get it.

For example, you can learn skills with your World of Warcraft gold. You begin by speaking with Mordenai in Nether-wing Fields (southeast corner of Shadow-moon Valley). He will send you on a chain of quests designed to get you neutral with the Nether-wing faction.

After you are neutral, he will talk to you about infiltrating the Dragon-maw Army. He will then send you to speak with Overlord Mor'ghor, the leader of the Dragon-maw. He is located at Nether-wing Ledge.

Life as a Fel Orc: You will change in appearance when you get close to the camp. This is because you are working as a spy now. This spell, which changes you into a fel orc and your mount into a nether-drake, will cause all of the fel orcs to become friendly to you. It is only in effect in the vicinity of Nether-wing Ledge.

Once you arrive and speak with Overlord Mor'ghor, he puts you to work by sending you to get tasks from Taskmaster Varkule Dragon-breath. This is where the new quest types come into play.
