How to complete geirmunds hall

[WeylandYutani]

I cant complete this location, i have the quest with forbidden story thing found the book in this location and i completed this dungeon kill the boss etc but the location doesnt complete. Is there any reason for this ? like another quest ? the forbidden story quest doesnt start in geirmunds hall there is another location for it so i dont understand why it doesnt complete.

Edit: i loaded a previous save and dont jumped down, the book for the quest lies before you must jump down so i do the legend quest first before going back in the dungeon. But there is a ban magic formel on near the dead magic guy do i need it for the forbidden story quest ?

Edit: I mean Forbidden Legend quest not story

Edit: ah ok it seems that you must do start the legend quest first and then search for the amulett parts to complete these dungeons.

you have to join the college of winterhold, then you go on quest with college to saarthal. You can only enter Saarthal through College quest-line,,, in order to get the third amulet.
