It's a simple mission, really. I would go myself if I could. Bring the ailing duke to some healing springs. So, there's some disputed territory along the way? That's nothing! The possibility of some trouble with the local fauna. Nothing to worry about. The duke's ailment? Nothing, truly. He can take care of himself. A walk in the park for such stalwart adventurers as yourselves. Trust me. It's easy. Really. GURPS Banestorm.
