Kepral's Syndrome is a genetic disease found only in drell. It is named after the drell scientist who first diagnosed it, and it has since been an issue for most members of the drell species. The disease itself causes erodes the ability of the drell's body to properly consume oxygen, as well as stops the blood from producing hemoglobin, and is caused by cumulative long-term exposure to a humid climate. This caused drell lifespans to shorten drastically, and has become the leading cause of death in drell, with the lungs being slowly eroded until the afflicted can simply no longer breathe and suffocates. The disease is not hereditary and it is noncommunicable, meaning only drell born in humid climates have a high chance of getting it, and drell cannot pass it on, as the disease is not contagious.
By2186 CE, no cure exists for it, although hanar scientific authorities have been working towards one.
