I was a spy, a traitor to the enemy.

Hardly any know your true name and true part in the war. Most who did now are dead and the few left have been sworn to secrecy on pain of ****. You masquerade as a simple decorated nobleman with a few honours to your pseudonym.
Your line has been loyal to the current royal family for generations and each of your predecessors have managed to put them enemy at a serious disadvantage.
You however, have outstripped them all. It was your secret network of spies that alerted the generals to the enemy's ambushes and hidden stores. It was you who infiltrated the opposition's royal house and learned the enemy's plans from the very moment they were formed.
You betrayed an enemy prince and compromised their entire fleet by planting false information.
Indeed, you have worked hard and well, albeit in secret. You deserve some time off and how better to spend it than with your prize?
