A/N: I learned while writing this that caustic creepers are a type of plant... be prepared for a potential sub species. This is also something that's been just sitting here for a while, but I couldn't figure out what I wanted the Caustic Creepers to look like.

Description:

Caustic Creepers, also referred to as 'those that lurk in the gas,' are gaseous wraiths that produce toxic gas, with said gas being of variable make up and toxicity. They can also possess either their original body or another dead body, but they are capable of taking over a living being, if the being has just inhaled enough of the gas that makes up the "body" of these spirits

These spirits are created when a sentient being is killed and the body is left to rot, with the Caustic Creeper only being born if the body builds up enough gas on the inside. One of the easiest methods of preventing the birth of these spirits is by honoring the dead by collecting their bodies from where they died so that they can be buried and receive what they need to pass on in peace or by hacking them to pieces

WARNING: Cutting slits or shooting holes into bodies that are potentially going to become Caustic Creepers is one way to prevent them from forming, but this can also speed up the process by giving external gas a way into the body. Destroy any suspected bodies with fire and/or by cutting them into pieces and then scattering the parts.

Cool Facts:

- These spirits don't need to eat, breath, sleep, or defecate

- These spirits were first discovered by an artist who was observing the field of a recent battle so that they could have reference for a piece of anti-war propaganda

- These beings are sentient, but they don't retain the memories or the personality of their original selves once they become a spirit
