Most Noble Leader,
A representative of your region who may speak on behalf of your crown is requested to meet on the second evening of the third new moon in the Celestial Hall of the Imperial City. As to the reason, forgive my silence, but know that it is a matter of urgency worthy of your immediate attention.
Please send your representative with this letter, bearing my royal seal, as proof and intent of your committment.
My appologies that I may not meet you in person. This matter requires me to remain here. I offer my well wishes to you and your kingdom with this courier in my stead.
