The Styrian Kornberg Castle is old. Very old. It protected from the Hungarians, came into noble hands and was repeatedly rebuilt and extended. Of course, this cost a lot of money and who knows what would have happened if it hadn't been for the very young Herr von Stadl and the old Gallerin von der Riegersburg ..., but that's actually a completely different story. 
 Anyway, there has always been a secret gate in the castle wall. It was so secret that nobody ever knew about it, not even the counts. And so Santa Claus always manages to leave the castle unnoticed to bring presents to the children in the Riegersburg area.
