Lambency

The lambency disease is a parasite that multiplies rapidly and takes over host. It is an old Locust disease that can spread to other species as well.
The disease spreads in multiple ways. Either by long exposure to the source mineral in which the disease lives, long exposure to someone infected by lambency or direct contact with lambency liquid.
The disease exists out of 4 stages. These being infected, rustlung, weeping and Lambent.
== State: infected ==
When infected, your body wouldn't act any different than normal. In the worst case there would be a slight fever of your body fighting the virus. In here, there is a minimal chance for your body to kill the parasite before it can multiply.
State: rustlung
During this state, the parasite managed to get in your blood and is multiplying rapidly. This is mainly noticeable by the fact that the victim's lungs begin to feel dry, making the victim cough a lot. Victims mat experience this feeling as if the lungs are rusting, and the coughing contains the parasite, making it already infectious at this stage.
== Stage: weeper ==
In this stage, the virus spread through the body and is attacking the brain, trying to take it over. The victim will still be conscious, but in severe pain. The blood would have been replaced by the lambent liquid, making the victim dependant on the virus. During this stage, the victim will have no energy to fight or move. Outsiders say it is very similar to a walking, glowing corpse.
== State: lambent ==
When a victim has become lambent, the virus has taken over and the body came under the control of the virus. A lambent person mutates in horrible ways with the sole purpose of spreading the disease. They become aggressive and violent and will attack anything within view that isn't lambent either. Upon death of a lambent creature the body would explode in a last effort to spread the parasite
