A message written on large placks, notice boards and as flyers is sent throughout out almost every settlement on Kalimdor, and likewise reaching Eastern kingdoms as well. The message is unsigned, because it obviously doesn't need a signature, its meaning clear enough:
Attention all able-bodied members of
the Horde! Warchief Garrosh Hellscream has
issued a CALL TO ARMS for all citizens!
Male and female adults! You will
train to fight the Alliance in a WAR
In which we shall be TRIUMPHANT!
Children and others who cannot bear
arms - you will assist in crafting weapons
and tending to the needs of the WARRIORS!
Anyone found shirking his or her duty will
be ARRESTED for TREASON by the Kor'kron
NO EXCEPTIONS.
FOR THE HORDE!
