I have taken the last dwarf´s book of artifacts, and collected all of them, but I can´t find the daedric crescent. Is there a trick? (Question for real freaks; no cheats!)

The Daedric Crescent is in Magas Volar. Magas Volar is only accessible through the Tower of Tel Fyr (as marked on your paper map). Once you're in the Tower of Tel Fyr, head on up to the Hall of Fyr. Find Divayth Fyr (he's the guy in the full Daedric Armour so you can't miss him ^_~) and look on a shelf to his left. You'll find a "small ornate lockbox" with a low level lock. Open it (don't wory Divayth is quite oblivious) and equip the amulet you find inside. You will then be transported to Magas Volar. Kill Lord Dregas Volar (the Dremora that's probably flinging nasty spells at you by now) and you will be transported back to the Hall of Fyr. The Daedric Crescent will be added to your inventory automatically.

~Have fun~
