It reads as follows:
Lord Wynton, we are thrilled that you have located a surviving regiment of soldiers. With this new force, we can turn the tide and save our city. Your disagreements with the crown are well known, but we are glad you can put them aside in this dangerous time. Long live Westmarch!"
