Up until the end I was thinking "Everyone has an evil twin". Should've played the game through before jumping to conclusions... and attacking my brother.
I got past the first area, paid for map reveal and answered riddle. Than grabbed quest for Power when I wanted Riches. So I reloaded save and found out: already solved riddle (but dont have the gold) already bought map reveal (but map is no longer revealed) and I can't grab Riches quest. [3/5]
