Despite his weakness as a leader, Murdoch has inherited his father's powerful connections. It would be unwise to launch straight into this extreme course of action so early into your reign. You need more back-up first.
Now you are King, you increase taxes on land and on exported and imported goods. You introduce new, more formal laws that prosecute the guilty and protect the innocent. The guilty are all those who disrespect your rule.
You have returned to Scotland but miss the English courtly life you have grown accustomed to. You get in touch with Henry V of England and request he send a substantial group of English nobles to join you. Gradually the 'civilised' court will engulf existing Scottish nobility.
Which card will you play?
