“ How can you protect yourself by carrying a sword if you don’t know how to use it?’Not me, sir. Other people. They see the sword and don’t attack me,’ said Maladict patiently.Yes, but if they did, lad, you wouldn’t be any good with it,’ said the sergeant.No, sir. I’d probably settle for just ripping their heads off, sir. That’s what I mean by protection, sir. Theirs, not mine. And I’d get hell from the League if I did that, sir. ”
