Von Leon, the Lion King

Now that much of my strength has returned, it is time I faced Von Leon in his castle. I want answers he has.

Has Von Leon kept his secret passage from his days as a commander? I imagine he has. I'll go to Castle Entrance of the Lion King's Castle, and use his secret passage.

I have no idea what I will face in the castle of Von Leon... Perhaps I should take time to prepare.

Von Leon has blocked up the passage. How can I reach him now?
