From publisher blurb:
Six Lineages
Sylveeri. Sylveeri are the wardens and tenders of the gardens, fields and forests of the heavens, that regularly travel away from their homes to care for other natural worlds.
Astrelenae. Warriors of starlight, Astrelenae consider it a duty to leave the heavens at least once in order to enlighten and defend the weak among what they commonly call the "People of Below".
Ferynean. Feryneans are never supposed to leave their well-mannered society in the high skies; but when one of them starts becoming too curious about the outside world, they will be considered a risk to the community and casted out, condemned to fall off the heavens with shooting stars.
Herox. Heroxes are born for greatness: celestial beings born from divine parents, they turn into warriors, protectors and leaders of the heavens, or any other realm where they feel like they can accomplish their grand destiny.
Pythaix. Pythaix are the guardians and archivists of the knowledge held in the heavens and astral planes, but they sometimes leave their libraries to explore other worlds or may get casted out if they ever reveal forbidden information to outsiders.
Daemen. As the frontline defenders of the heavens, sent to fight against or deter threats across the various realms of the skies, Daemens are always at risk of getting dragged down to other planes by their enemies with no clear way to go back home.
