The World is Ending
Leave or Die
The End Is Near
You are all going to die. The Malaria virus will kill you all. The survivors will be too weak to fight and you will fall at the hands to the vikings. They will kill every one else and no one will survive.
Malaria
This disease has no cure. When you are infected there is no hope for you, you will infect anyone you come in contact with and die a slow death.
Vikings
The vikings will dock in these ships and that is when the world will start to end. They will concur our weakened army and we will die.
