I have fiddled with various camera angles and zoom for about half an hour there. It really made me mad that I will have an unfinishable quest in my quest log for the whole rest of the game, so I really tried. No luck.
Btw, the head is placed randomly in the castle. Every time you start a new game, it will be elsewhere. But of course, I don't want to start a new game, since I am quite far already. :evil:

Try to upload a saved game somewhere: we can try to see if our version (1.64, 16b7...) or style makes a difference in picking up this head

... however, i recall having experienced teh same issue with a might rune somewhere in an underground ; impossible to access...

Thanks for this offer but I'd rather do this another way. Exchanging my save between various versions seems risky to me. Even if it helps (which I doubt) it could break something else.
I was hoping for something like a mod or maybe a cheat to finish this particular mission.

Ok, I suffer from short term memory loss... (don't laugh, its true! ok, its kind of funny) but I have this quest in my quest log and now I can not find where the stupid castle is at... I thought this was in Verlon Forest but I can't find it, help please?

Yes, it's in Verlon Forest. After zoning in from Greenwort, just follow the road staight past the crossroads a short way and it will be on your right.

Great, thanks

So is the reward really a measly +52 leadership? Because I got the chest from the castle and I can't be bothered fighting the remaining armies inside if that is indeed the reward.

EDIT: I gave him his head back and got nothing. Go figure.

He is telling about this secret entrance via using one of the torches...

Reward is random.

First time around, I got a banner and a chest with gold.
2nd playthru, I got a banner and a chest with 2 mind runes :)
