Before the final wars, these creatures were a nuisance. They would lay their eggs upon the coats of various species of animals, especially cattle or similar large herbivores in the summer. A female could lay upwards of six hundred eggs on a single victim. The eggs would hatch in about a week and then the larva would burrow into the body of the herbivore. From there the parasite would burrow, eventually reaching the spinal column of the hapless creature, consuming as it went.

Radiation and various toxins have mutated these flies to the size of chickens, and can weigh about five pounds each. They are thankfully far less common than their ancestors but still pose a risk to not only herbivores but pretty much any creature.

They will swarm any warm-blooded creature they find and bite it, injecting a paralytic poison. Once the victim has been suitably contained, they will then land on the creature and burrow into the victim’s flesh, causing 1d6 damage per fly. What makes this far, far more dangerous is that the creatures will also inject a toxin that will cause the victim to lose all memory of being attacked. They will see they have suffered bites but that is the extent of it. Anyone burrowed into is allowed a saving throw versus energy. If it succeeds, then they know what has happened and can take precautions to prevent a horrible death. Each fly will inject 1d10 live larva into the victim’s body and that is when the real horror begins.

If left unchecked the creature would eventually sicken and die, allowing the larva to continue to consume the remains. For every day the larva infest the creature, it must make a saving throw versus poison or lose 1 point of Constitution per 5 larva. The creature also cannot heal any damage it has sustained during this period, so it loses its natural healing rate per day.

Once the victim’s Constitution score reaches zero, they will die and the larva will continue to feed upon the corpse until nothing is left internally. The body will look like a horribly withered mummy, with the skin hanging loose off the bones. Examining the body will reveal that there is movement beneath the loose skin and if it is cut open, the larva will attack anyone nearby. They have but 1 hit point and an AC of 7, and will inflict 1d3 points of damage as they attempt to burrow into the body. This takes 1d4 rounds and can easily be killed. If the creatures burrow into the body however, they will continue to burrow straight for the organs, inflicting 1d6 points of Constitution damage per round. Once the Constitution score hits zero, the victim dies.

Modern medicine which heals, when injected into body, will not harm the creatures, but it will heal hit point damage. There are several methods to remove the larva from the body. A low level poison can be injected into the body. This will harm the victim, but at the same time it will kill the larva. Radiation will likewise kill the larva and so will mutations such as vampiric field.

Secondly, the victim can be operated upon. This will inflict an initial 3d6 points of damage, and then will cause an additional 1 point of damage per larva that has to be removed. It is very easy to track the larva once they are inside the body, from the damage they have inflicted through consuming the victim. This is typically a method of last recourse, as victims are usually too far gone to be saved.
