Original Description:
 
Concept art: Miasmatic Glasses. Miasmatic glasses were developed by Thorn (my character)  
from an old flight goggle found inside a heap of old things from  
his new home in Canterllot. The glasses have an interesting property which is to filter  
the miasma gas that comes out of the protagonist’s eyes. A filtrate occurs through two side hoods  
on the part of the glasses frame and the miasmatic papers that are a type of polymer capable of transforming  
miasma in amounts of CO2 through a reaction that takes place within the cells of the Miasmatic Spines.  
This is the first developed and may undergo significant changes.
