Dearest ████████,

January 17th, 1936

  Congratulations! You have been selected for induction to the Society of Historical Recovery. Your skills and abilities have long been observed and have been found fit for our organization. We would like to invite you to our opening ceremonies taking place in █████████████, where there will be refreshments and amenities available. 

  Unfortunately, the celebrations may be short. We have received word that the Japanese paramilitary group, ███████████████, has discovered the fabled █████████████ and is en route to Peking by way of rail through Manchuria. A plane will be at the ready to bring you and your colleagues to █████████ and using your aforementioned impressive skills and abilities will secure said artifact from the hands of evil.

  We thank you for your cooperation and immediate response to this letter.

Sincerely,

Z
