Feanav

Feanav is a plane that has largely been conquered by a human empire, which is now at its peak. With the empire's recent mastery of alchemy, it is now in the early stages of industrialization. Feanav is the setting of Feanav: The Apothecary's Progress.

Celestials
Preceding human history, Feanav was inhabited by a nation of beings known as Celestials, who claimed direct contact with Feanav's creator. However, following the appearance of humanity, the Celestials developed into three broad categories of beings: Angels, Fae, and Demons. Each reside in subplanes coterminous to Feanav, but normally inaccessible to humans.

Fae
Early in human history, a celestial named Wormwood, "a great star on high", observed human suffering, and pondered its nature and cause. Upon reaching an epiphany on the nature of evil, Wormwood was overcome by the knowledge, and fell from Heaven into the sea, where it became the first fae. This event is known as The Bitter Starfall, and marked the first divergence between celestials. Following Wormwood, many celestials became fae after a similar loss of innocence.

Fae are not inherently evil beings, but they are often spiteful and dangerous. Many resent humanity for their fate, and some feel jealousy or pity towards humans. Fae are not properly mortal, and feel the weight of many years and reincarnations. Some find company by communicating with plants and animals, and others find sick amusement in tormenting humans.

Imperial humans fear fae, and have maintained a variety of traditions meant to protect against them. One tale asserts that more fae are created from the transformation of stolen human children, who are replaced by younger fae known as changelings. Fae are known to be protective of their names, and humans often refer to them as fair folk. Similarly, humans do not have a proper name for the fae subplane, knowing it only as the Fae Realm.

Angels
Angels claim to be the original pure Celestials, and maintain that they are servants of Feanav's creator. They reside in Heaven. Angels hold a rigid set of ideals, to which they demand conformity from humanity, such as hierarchy, social roles, and virtue. Since an angel that earnestly considers the state of the world is likely to become a fae, most angels maintain their innocence through willing ignorance of suffering, in particular their responsibility for it.

Demons
Demons are residents of the Abyss who desire nothing less than the complete destruction of all creation. Where fae might be insufficiently innocent to be angels, demons are actively malicious, and enjoy cruelty. New demons are capable of manifesting during events of profound destruction, including that which they cause. They are antithetical to angels, who justify their demands for humanity's conformity as necessary to defeat the Abyss. Fae similarly despise demons, but will not interfere with their attacks on humanity.
