The Flood[edit]

“One single flood spore can destroy a species”

-Rtas ‘Vadum

Physical Description[edit]

An infection form with a human host

The flood is a most insidious parasite. Their bodies are made of extremely adaptive supercells which take the appearance of malleable green-yellow “flesh” with red, flowerlike stalks. They lack standard means of reproduction, requiring them to infect other races, reducing the host to pure biomass which then forms more flood. Though it is possible for this process to take place in less intelligent wildlife, and even plants, the flood prefer to feed on intelligent races, as they are the key to forming a gravemind. Each member of the flood can take one of three forms, though they are not necessarily bound to that form forever. The combat form, or pure form, is the product of completely broken down biomass being used to create a hulking body capable of extreme punishment. The infection form is similar in origin to the combat form, but instead is a bulbous, oblong, skittering organism roughly the size of a human head which can “possess“ and convert other creatures into biomass. Finally, the gravemind is a biological supercomputer in charge of commanding entire flood colonies. They are typically stationary with a mass of writhing tentacles. As they are only able to grow by consuming intelligent life, they tend to initiate a “harvest” system, in which they allow life to flourish until they are deemed worthy of consumption. All flood weigh roughly 1 ounces per square inch.


As they were pushed to extinction, a highly advanced race known as the Precursors sought any means of survival. In their desperation, they became able to regenerate from dust. Over thousands of years, this dust became corrupted, forming the flood. Many races who’s names have been long forgotten have been consumed by the flood. After each harvest, they retreat to the farthest corners of existence, waiting for the next sentient race to come to fruition.


The flood are a hive-mind. Each individual infection or combat form has little to no intelligence. However, when in greater numbers, especially with the inclusion of a gravemind, they become smarter exponentially. Despite the level of their final intelligence, all known colonies exist for the soul purpose of consuming.

Flood Names[edit]

While flood do not necessarily retain names, an advanced enough colony may name itself after the Precursors it originated from, or the name of the greatest intellect it has integrated.

Examples: Primordial, Didact, Librarian, Faber
