In this time, the events following infection by a strain of fungi are revealed

1834, May 1st: A British scientist, Louis Pakenford-Smith discovers a strange fungus in the depths of the Amazon rain forest.

May 4th: One of his colleagues, Dr Henry Ryaningham develops signs of an infection after he accidentally inhales some fungus. His temperature rises and spores begin to form on one side of his face.

May 5th: Ryaningham becomes bed-ridden in a tent. Spores appear on his arms and upper torso. They spread around his body.

May 9th: Ryaningham, who for days has been coughing up foul smelling globules and has had a high temperature, dies. His body is now almost completely covered in these spores and he is now virtually unrecognisable.

May 10th: Pakenford-Smith and the members of the expedition are about to set off on their way home. Then suddenly a scream sound from Ryaningham's tent. Then a creature completely covered in fungal growth emerges carrying the lifeless body of the expedition surgeon, Grayson. The men fire at the creature. The bullets have no effect. Then Pakenford-Smith chucks a lit torch at the creature. The creature bursts into flames and collapses on the ground. The members of the expedition flee the scene. The burning creature then explodes, covering the nearby trees with globules of fungus.

May 17th: Pakenford-Smith concludes that the fungus was, in fact, Ryaningham, who must have been infected by the fungus he inhaled. However before he can reveal this information to the world he is killed in a flash flood along with the entire expedition.

159 years later

1993, May 1st: A team of scientists working for RPC (the Richmond Prosperity Corporation), led by Dr Lukas Wallis collect a sample of the fungus. They transport it back to the corporation's laboratory in Richmond, Virginia.

May 11th: The fungus sample arrives back in Richmond. It is stored in a room with supposedly 0 degree temperature, as they believe, that that will not affect the fungus.

May 12th: Wallis and his assistant, Dr John Fielder begin studying the fungus. They do not notice anything dangerous about the fungus, but that is probably because they are wearing highly protective clothing.

May 14th: Joseph Tamner, the 67 year old founder of RPC arrives to inspect the laboratory. He tells doctors Wallis and Fielder to see if the fungus has any special properties that could make it useful for the company.

May 15th: Wallis and fielder test out what happens if the fungus is put in a room with a freezing temperature. However that night, there is a power-cut in the building. This causes temperature control inside the building to go haywire and instead of freezing, the room heats up and the fungus explodes across the room in which it is stored.
