Ash-adjusted sylph are stigmatized by Llyran society for their abberant ability to breathe unfiltered Erjan air with no ill effect. While indeed, the ash-adjusted are unlikely to die by prolonged exposure to ash, one would be incorrect to assume it's at all a simple thing. Ash-adjusted sylph may endure a host of unpleasant side effects, a partial list of which includes itchy eyes, sore throat, nausea, disorientation, chronic bronchitis, sleep apnea, fatigue, migraines, audiovisual hallucinations, post-nasal drip, loss of impulse control, aphasia, temporary blindness, suicidal ideation, and dry stool.
For many of the ash-adjusted, it's easier to just stay home.
