I fear there is no solution for my problem, but I will ask anyway...

Right when I want to rescue King Richard, I found out that I lost one of the keys needed to do so. I have three of them, but it seems I accidently lost the fourth one somewhere during the game.

So is there any way to rescue him without the four keys? Somehow I don't feel like going back and search all maps again to find the one lost item.

Thank you for your offer, but that would feel to much like cheating to me. I think I'll have to admit that I was defeated and Scotia has won.

Yesterday night I felt a little frustrated, but now I think that I had a good time with the game and I will probably start again in some months and try to win with another character.
