Halothorne Vapour

"And from the crushed remains of the thorns, came fine vapour. The steam would rise, and the Order shall claim it in fine bottles. From there, they shall come to the towns of corruption and decay, and let the people of it become free. Their freedom, in Saint Hypnos' name, shall bestow to them a peaceful transition to the lands beyond. Only then, shall their work be done,"
 

- Excerpt from Saint Hypnos' Order of Slumbering, on the use of Halothorne Vapour

  Halothorne is a form of plant that grows specifically in the lands controlled by Saint Hypnos' Order of Slumbering , a small group that lingers in tiny numbers across the more diseased regions of Aitso, such as the Thevagon Isles, and Scylla. The plant itself, in nature, had only grown off of a miniscule island that was devoured by the ever-growing chasm that rested below Malus' domain. What was left of Halothorne, the very few seeds and stems, had been collected by all of the remaining members of Saint Hypnos' Order of Slumbering , in order to be preserved and kept in the hands of good people.  
  Halothorne is known across many regions as being a miracle cure for suffering and despair. It functions as a severe anti-depressant and, in greater forms, can even be used as a method for euthanasia. The vapours collected by crushing the plant can cause people to simply drift off to sleep - and potentailly never wake up. This form of care is treated with high regard, by the dozen or so members of the Order of Slumbering, and must be used in only the most dire of times.  
What makes Halothorne as unique as people say it is, is the amazing smell that comes from the plant. Since smelling copious amounts of the vapour causes death, the smell is known as being on many people's bucket lists. Those that smell faint traces of it describe it as being similar to lavender or rosemary. Due to this, the smell is often diluted with lavender and rosemary, for recreational consumption. The smell, whilst not inherently unique, offers its capability of a painless death in a way that is not seen with other odours and substances. The smell is common, but the traits of the substance is what makes it truly unique. 
    Many say that the smell itself is hypnotic, and that even simulations of the smell, through magical altercations and illusions, can be reason enough to understanding why Halothorne Vapour is incredibly sought after. Different replications of the smell have reached further than the Order of Slumbering itself. Often, markets that host shady merchants and clerks use illusory smells in order to coax people into buying their 'limited edition' Halothorne vapours, despite having no method to gaining the vapours themselves.
