there are even eggs that spawn along the ridge

This is the only completely repeatable Hellgate London palladium quest there is, and it's to turn in a nether wing egg. These eggs can come from anywhere herbs, mining, Hellgate palladium mob drops, there are even eggs that spawn along the ridge that you can click on to loot. Sadly though, the drop rate on these is incredibly low, I probably only got 15 or so during the Hellgate gold entire rep grind. I'm not sure how common the loot able ones will be once the servers are live, I think they take a while to spawn and the server wasn't usually up long enough for them to show up.
Ok this quest can be difficult if you Hellgate Pd in stock don't know what to do. Basically you have to channel a spell from your gryphon onto xxx subdue a 73 elite in twilight ridge in nag and.
What you have to do is keep far enough cheapest wow gold back from him, and dodge his bolts to eventually drain his life down, I found it easier to train him around the center of the camp keeping across the center from him at Age of Conan power leveling all times (note: height has nothing to do with melee range so don't try to just fly high enough that he won't melee you).
