I cannot equip wraithguard artifact, I even showed Yagrum Bagarn the Kagrenac's planbook and K. Journals but the dwarf doesn't want to equip the artifact. I even went out for a sleep of 8 days outside the building and even then yagrum Bagarn doesn't repair or equip it. He says only that its too risky for me. (my level is 11 and my health is perfect) What can I do? Please HELP!!!!!!!!!!!

You have to have Health of at least 201 in order to equip the modified Wraithguard. The first time you use it, the modified Wraithguard does between 201 and 225 points of damage to your character. If you have more than 225 Hit Points, you are all right. But if you have less than 201 Hit Points, you will have to level up before you can proceed. Since you are only 11th Level, I assume that you do not have a high enough Health to proceed.

and how did you get that stuff from Red Mountain at Lv11?

by luck there is a small chance of survivavl though enemies are placed pending your level so the comp will only generat enemies that it thinks judging by your skill level what you can take.

true King but only way to do it all at level 11 is through glitching the character due to the fact that you can only get the inactive wraithguard from Vivec

Thanks rbmoney and all the dudes!!!Just one question, what can I do in Morrowind when the main quest is completed?
What do you recieve at the ending from Azura?
I heard it was a ring, waht can I do with that special ring?

Once you complete the Main Quest, you have several options. You can go and complete the Faction Quests and the Miscellaneous Quests that you have not performed. You can explore the island and hit all of the random dungeons that you haven't visited. You can try to acquire all of the unique artifacts in the game. I prefer to rise to the head of one faction per character and then complete the Main Quest. Then I'll start over with a new character choosing a new race, new class, and new birthsign. Generally, if you can complete the MQ, you can beat anything else in the game, and I prefer the challenge of developing a new character. But that's up to you. You get the Ring of Azura from her once you complete the Main Quest. It has Constant Effect Night Eye and Restore Fatigue enchantments. A nice ring, but you can create much more potent rings yourself.

Can I also join Dagoth Ur?
Or can I only destroy him.
And what can I do when I can join the bad GOD?
You know, the guards don't like me and people don't speak very nice to me, so I wan't to join the ruler of the red mountains. Is that possible?

No, you can't join Dagoth Ur. You have to fight and kill him to complete the Main Quest. I hope they put an "evil" Main Quest path in the next Elder Scrolls game. It would have been cool to join the Sixth House and fight the forces of good for Dagoth Ur.
