Like many cultures, the societies of the plantoid people have dealt with the matter of ghosts. While views in individual cultures and religions have varied over the eons, the contemporary view of non-living souls has settled upon many commonalities for most plantoids, provoked by both globalization and shifting attitudes.
Overview:
A ghost is a soul that is not associated with a living body, but either has the potential to be associated with one, or has already been associated with one. In this manner, ghosts are intimately tied to plantoids, and other species have their own ghosts. A ghost is by definition involved in some state of phenomenal existence. They are incorporeal, invisible, and have varying degrees of ability to interact with the world of the living. This can include, but is not limited to, the ability to move objects, to cause strange sounds, to induce visions, to communicate with people, and to provoke numinous feelings.
Categories of Ghosts:
Numi: Numi are ghosts who have never taken a body. They are referred to as ghosts because they still occupy some sort of phenomenal existence and have the potential to be born as plantoids, which in matters of eternity is interpreted to be nothing less than a guarantee. As they have never been alive, Numi are taintless, alien in mind, and powerful. Numi are the furthest of all ghosts from men and are thus often feared the most. Sometimes ominous events or poltergeist activity in a home for no apparent reason is interpreted as the fell presence of a Numi. Because of the strength and foreigness of the Numi, the period of time before a child has been born is regarded as an especially dangerous time. Traditionally, the Numi is placated with various rituals and offerings prior to birth, and upon the child's arrival into the world, the family celebrates the capture of the former Numi. In past eras, the death of people in infancy and early childhood was interpreted as the still Numi-like soul escaping due to disatisfaction with life.
Yeno: Yeno are ghosts of the dead who remain on Earth. Yeno represent the most common vision of the ghost and are the ones most likely to be depicted as such in media. Yeno are shaped by their experiences in life, and are the most comprehensible to the average plantoid. A Yeno's disposition, likes, dislikes, qualities, attitudes, and way of being are directly influenced by how they were in life, and this also indirectly affects their abilities and stature in the afterlife. It is for this reason that most Yeno are believed to be weaker than other supernatural beings and their ghostly cousins, but it is also held that a life of drive and conviction can serve to produce a being stronger than even a Numi. It is generally thought that Yeno have some bond that keeps them tied to the Earth, though this can be more abstract than simple earthly desires or mortal connections. Yeno are the easiest for the living to interact with and thus serve as the primary target of necromancy. However, their solitaire nature and hidden bonds prevent them from being the target of ancestor cults. Of spectral phenomena, Yeno are most commonly associated with strange sounds and whispers.
Vani: Vani are ghosts of the dead who dwell in heaven. Vani are generally the most tertiary category of ghost, and often overlap with gods and spirit-conceptions of souls who dwell in higher planes. The main distinguishing factor of ghosthood for Vani is their ability to communicate with the living. They are held to be stronger than most Yeno, but they are cleansed of many earthly concerns and are thus less personable to plantoids. Vani serve as the object of reverence for ancestor cults. Of spectral phenomena, Vani are most commonly associated with visions.
