Just to add to the very helpful post above, this is pretty easy to solo. I had never been to the instance, however, so I didn't know what the North entrance was or how to get there. I'll try to clarify for complete noobs like myself.

As you come up to the main entrance, which is marked on the map, you'll go up a ramp which has an ogre at the top. There are walkways to the left and right, but you want to go straight through the big doorway and into a hallway that turns a couple of times ... there's only one way to go here, so just follow it. I was level 56 and I was able to go around the ogres without aggro. Watch out for patrolling packs of dogs, they're pretty frequent.

At the end of the hallway there's a giant door-looking thing, but you have to go around to the back of it to continue. It's pretty clear on the map. When you get around and through there's a giant open courtyard with a sunken forum in the middle and ogres all over. I stuck to the left wall and was able to get past all the ogres. Go all the way north here to find the door.

At the north end there's a ramp that is guarded by a couple of ogres that are a little too close to sneak by, at least at level 56. At this point I used my pet to distract them and ran to the door, feign death.

Here you either need a crimson key, which you can't solo, or you can use a powerful seaforium charge (if you're an engineer), which worked like a charm. Keep in mind that you'll need 2 of them, one for this door and one for a door in the instance. Behind this door is the start of the instance.

Once in the instance it's a short run to the door you need, but it needs to be well timed. You're looking out of an alcove in the wall, and slightly to your left is a ramp down into a central area. Watch the patrols for a little to see the pattern...there's a single ogre that moves right and left. You want to go when he's to the right. There's also a patrol of an ogre with 2 dogs that seems to wander around the whole area.

Once it's clear, run to the ramp and jump as you're going down the ramp onto the railing. You can't jump straight onto the railing, it has to be as you're going down the ramp...angle slightly to the left. You want to land as close to the beginning of the railing as you can. The group of giants there won't aggro you, but watch out for a patrol of dogs, they will aggro if they're close.

From the beginning of the railing jump down and hug the wall to the left. The door is right in front of you now. Just follow the wall around and go down into the doorwell. Another seaforium and you're in the hallway to the library...no more mobs to worry about!

Remember that you have to right-click the book to start the quest, and also pick up the pattern: mooncloth robe from the vendor in there...you can make a few gold in the AH.

The reward is the Royal Seal of Eldre'Thalas.

The only version available on thottbot is the mage version, but each class gets their own version of this.&nbsp The hunter version has the fire resistance, as well as a +48 to ranged attack power.&nbsp I've been told there's actually three possible ones for each class, so you may get one slightly different, I'm not sure.

The library is in the west wing I've found, but there may very well be passage to it from the north wing.&nbsp To get there from the west, work your way through the first room, around to the other side.&nbsp Down some stairs, you'll meet Warpwood, the ancient, who you'll have to fight.&nbsp Past him is a doorway to a corridor full of spirits.&nbsp They're not that bad, and you can fight through them easily, but they tend to spawn another one or two as they die, until you've fought three in a row, non-stop.&nbsp Past that is the Prison of Immolthar.&nbsp You have to fight a couple nasty air elementals, but work your way north once you enter the room, and there'll be another passage.&nbsp Through the door there is the library where you drop off the book.

You can solo this...You will need the crescent key to get into North Entrance and The Left Courtyard Door.

Sneek your way into DM..go to North Entrance..wait for patrol to pass..head halfway down ramp...if you go all the way down and try to cut left you will draw agro...so running jump on to the left side railing of ramp...Drop down to courtyard from ramp railing...walk over to left couryard door..open with key..follow the long hallway to library..She is on the right..turn it in book to get your trinket..stone out!
