where is the dwarf electric thing for sprit Lina?

[Lathspell]

I just got there, but the area following the creigston mines (can't remember the name of the mines) is either bugged or restricted for me. No npc or tavern will talk to me, and I can't touch the device either. I can't get any of the quests here, can't enter the pyramid, can't visit the tavern for the Titan's Tear...Is it a bug or do I need to finish the main quest (visit the king) first?
