This is another good place for you to level up starting at level 45. You can come here at level 44 but you won't get the repeatable quest that rewards you with a Platinum Coin. This quest can be acquired starting at level 45 but you must do a pre-quest before doing it first. To see the Pre-quest click here.
The Coins are worth the trouble because they are used in getting some excellent gear at level 50. Even if you decide you don't want to use the coins on gear you can always sell them in the AH for a pretty decent price.
If you're keeping your gathering on par with your level you'll be able to find Ruby, Mithril, Orichalcum and Zeller in this area. There are quite a few different locations for the nodes in this area, as you can see in my video. This area gets my stamp of approval for excellent spot to gather and level.
This is the coin quest that involves killing the undead. You will need to kill the Undead for 54 Ghostly Spirit Stones. To put it simply, you'll need to kill 54 undead. Once you have all of the Ghostly Spirit Stones you will want to return to town and turn in your quest.
NOTE: There are more ghosts then what are just here, but they are a bit further away from town and if you're lower level you will need to plow through quite a few other mobs to get to them. Don't forget, if the channel you're in is too crowded you are always able to switch channels.
