Death Seed

This plague was virtually unstoppable when it was first discovered. It was caused by a parasite called a droch, which could steal life force energy from its host. If allowed to remain attached, the droch burrowed into its host and absorbed itself into the victim’s body. The victim eventually died of unknown, though obviously viral, causes. Bacta therapy only accelerated the disease, because the healing provided a renewed source of energy for the droch. It was later learned that the droch parasites were part of a hive mind, with a creature called Dzym as the leader.
