Ok.. I guess I can amend some things to this topic (since I started it) before going to bed
1) That scroll remains mystery to me as well, I got per 9 and don't see a digging place (which is why I completely missed this?)
2) Mines... OK everything got clearer after I found that door, completely MISSED it before, after some crazy sneaking... still missing her blood though. Gonna assume that involves later quest, either way, mines blown up. But... I am still confused... the log said "ancient magic" can kill them, so I guess they mean the spell I have now with her blood... well gee! Could have mentioned that in your log-book mr. dead immaculate dude in the mines ;p
3) The White Witch... that area is easy* after you figure out the barrier... and I rescued her after a nifty boss battle which was FAR easier when you outlevel the boss by 3 and have teneberium weapons..., now I have doubts whether I broke some quest by being this far ahead.. let's hope not...

I think I have been everywhere in Lucca forest except the area thats on fire and has void creatures ~.~ (I wonder if that spell can then kill THEM as well?)
So basically, I still don't know how to kill void creatures to end a rain of fireballs in my homestead (good news, now it actually heals me half the time ,p) ~.~
