Time flies while consumed in the art of consumable weaponry.
Poison
The world had an answer to the demonic entities that began to flood the world. The Dragoncorns made the uncomfortable decision to fight the demons with an equally destructive force. Nastusia had been willing and intelligent enough to try to outsmart the demons. The other Dragoncorns let out a sigh of relief and turned their attention from the demons to allow Nastusia to do whatever she felt was appropriate.
Nastusia could be found rummaging the edges of the forests, diving into the depths of lakes and picking out scraps from trash piles. In the very beginning she was often dismissed as mentally unstable. She would rant and rave about how she could find a deadly poison that could wipe out the demonic race without much fuss. No one believed her and soon she was spotted with a long beaked mask that she had stuffed with herbal remedies to filter the air. She was convinced that the air that escaped from the lungs of the demons was contagious.
It wouldn't be long, however, before others saw the genius of the poison solution. She would graciously lend her knowledge to the ones who were willing to scald their hands, test their elixirs and stretch their intelligence in the name of goodness and purity. The group grew slowly, but the intelligence of the members would form a solid base to grow upon. The adults would encourage the youth to excel at their studies and to surround themselves with whatever ingredients they could get a hold of.
The members are known to be reckless in the name of goodness and purity. They don't hesitate to use their poisons to destroy the demons. With fluid movements they effortlessly sneak into the darkest of places to discretely apply their poisons to the demons.
These days, they are well respected and feared by the other Dragoncorns for their intelligence. The Poison coven can be accused at times for being self centered and often times holding a grudge against the other covens. The poison coven had been criticized as crazy for ages by the other covens, but now that they've proven themselves they slink amongst the other Dragoncorns with a chip on their shoulders.
Nastusia surrounds herself with her coven and is rarely seen by the outsiders. She oversees the experiments of the eldest of the coven members. She's so elusive that she is often seen as a legend rather than an actual figure in the coven.
