Hammer of the Empire. Part 4

They called me the Hammer of the Empire. I was a general who saved the country—and then became a threat. Now I’m a prisoner doomed to eternal confinement. But a new threat has appeared—one against which the army and combat walking machines are useless. That’s why they remembered me. If I help, I’ll get my freedom and return what was long lost. And I have no doubt there’s a catch in this bargain.
