Are the tall walls around the courtyard important?
Answers:
1. If you could climb them, you might be able to escape the Beast.
2. If you could collapse them onto the Beast, that just might do it in.
3. If you could transmute them into steaming mounds of Qurmeesian Mega-Rhino flank steaks, the Beast might start in on those and ignore your few measly pounds of stringy flesh.
