The origin of the Blighters came from research performed in the Mauhúl Valley. It began with druids working on ways to counter the demons numerical superiority of the Demon Spawn War (8972 GE - 9493 GE). These druids were then joined by alchemists, and those skilled in dealing with diseases. They worked in a Covenant program that led to the development of a disease called the RT-12 Leech. Plants the vector, each new growth gave rise to an infected plant. A decade later, the plant vectors were all over the Mauhúl Valley. The area was so deadly to travel, that both sides avoided it. The research done in developing the RT-12 Leech and all its predecessors led to an understanding of how to tap the nature energy coursing through plants. This knowledge, inevitably misused, led to a branch of druidic study, Traditionalist Blighter, that power their spells by draining the nature energy around them.
Instead of draining the area around, Blighters can power their spells with Dark Nature Energy instead of Nature Energy. If one is up to praying to Melrith, this dark nature energy approach is often less restrictive and cheaper than consuming the nature energy around.
