Your costume suggestion
As the King of Scotland, you are clad in a thick red tunic to protect you from the arrows of your enemies. Over this hangs a tartan robe, which you wear proudly along with your hard-won crown. You carry an enormous sword.
Since an early age, resolving conflict with violence has served you well. Recently you were promoted to Thane of Cawdor and, through a precariously executed and bloody chain of events, managed to find yourself as the new King of Scotland. Actually, both you and Lady Macbiff stabbed the old one in bed in your castle. A modus operandi that’s looking a bit suspicious right now…
INTRODUCE YOURSELF AT THE START OF THE GAME BY READING THIS
All hail Macbiff, King of Scotland. Brave, courageous, and pretty good with sharp things. Yorick was my jester, so I was shocked to see him here. It’s treason to leave without being sacked or executed, so unfortunately for Yorick, it’s certain one of those would have come to pass. Alas, the blood is not on my hands - not for this one anyway. With parchment and quill, Lady Macbiff and I retired to bed early and were drawing positions I’d like-eth to fill. Forsooth, seats on the King’s council are available still.
