Dwarven Ruins Side Quests

Dwarven Treasure:

This quest begins when you come across the Extraordinary Demon, it can be in different locations so you have to hunt for it... however I usually find it at the X on the below map (it also seems to sometimes help if you go into the chamber and speak to the guard there):

Here is the Extraordinary Demon:

When it dies it will drop a Page of a Diary, which will go directly into your inventory:

Right click the Diary in your inventory and the following message will appear:

Clicking Accept begins the quest. There will be no Quest Flag to direct you, you will have to find the chamber yourself, it is at the location marked by the X on the map below:

Enter the chamber:

Inside you will find a Dwarf who is standing before a doorway with a force field across it:

If you happen to go and speak to him before reading the Diary he will say:

So anyway talk to the dwarf after you have read the Diary:

The dwarf will teleport away and the force field will disappear. The treasure is marked by the Quest Flag on the above mini-map, it is just a regular chest:

Inside the chamber there are many graves, guarded over by Sepulchre Guardians:

If you click on any of the graves the Guardians will all attack you:
