'Aslan a man!' said Mr. Beaver sternly. "Certainly not. I tell you he is the King of the wood and son of the great Emperor-beyond-the-Sea. Don't you know who is the King of Beasts? Aslan is a lion- the lion, the great Lion.'
'Ooh!'said Susan, 'I'd thought he was a man. Is he-quite safe? I shall feel rather nervous about meeting a lion.'
'That you will dearie, and no mistake' said Mrs. Beaver; 'if there's anyone who can appear before Aslan without their knees knocking, they're either braver than me or else just silly.'
'Then he isn't safe?' asked Lucy.
'Safe?' said Mr. Beaver. 'Don't you hear what Mrs. Beaver tells you? Who said anything about safe? 'Course he isn't safe. But he's good. He's the King, I tell you.'"
