Will I get the Tower after I get the "soul" back for the ghost who's been stuck there for 1000 years? I found him, the stone and the Ghost Merchant in the Tower, I have yet to get the soul back. Can I assume that he gives me the tower after I get his soul back to him?

If I read these right, the necromancer is outside the Tower now, inside later?

Only problem is, I've sold all body parts..Must I have them, found or bought, to build my creature. Or is it possible to build one from other "stuff"? Thanks
