Spirit

Generally speaking, a spirit is any unliving creature that defies the rules of the living and are based on the rules of the arcane. The term itself is most often misused, spirits referencing everything from the deities to demons and ghosts. Though this is not technically wrong, if an academic uses the term spirit, it is more often than not referencing a benevolent creature that originates from the elysian plane. Used in this way, a spirit is not the same as a demon but would be categorized alongside them due to being in the same taxonomic hierarchy: arcanea; but not the same phylum.
A spirit is any creature that was either created by the deities or was created in the elysian plane, an act that takes place every Hat'ein. The difference between them and ghosts is that they never lived. Their interest in mortals is only due to the wide range of emotions that mortals give off. While the difference between demons and spirits is that spirits do not need to constantly feed while on the mortal plane, they can simply exist and are drawn to places of high levels of magic and emotion. They flock to places that hold emotional scars, which is why ruins, battlefields, graveyards, and some festival areas will have numerous spirits.
Existing in the same phylum, the following are all different classes of spirits one might encounter: guardians, orbs, and possessed.

Guardian Spirits

Guardian spirits are rare to come across and seeking them out usually requires a journey or quest. They can be found in multiple biomes and are there as either protectors of the biome or protectors of the secrets in the area.

Orbs

These are emotional spirits that are filled with curiosity. They appear like orbs and drift idly with no sense of direction. The longer they stay on the mortal plane, the more cognizant they become and some will adopt the behavior of those around them. For example, there is a ruin near the Opal Warriors that hold a variety of spirit orbs. Three of these orbs have adopted personalities and rivalries with the other. They will grant a wish to any who come to them as long as they haven't accepted a wish from the other.

Possessed

Possessed spirits are those who have combined with the soul of a living creature. Unlike demons who can possess a creature without consent or prior knowledge, a spirit can only possess living beings under three possibilities.

1. The host gives permission, a feat that only a few sentient creatures can achieve. Those such as dragons, weres, and Maji are incompatible with spirits due to the level of magic existing within them. Alyrians can be possessed by but in doing so will shorten the individuals life significantly, the magic destroying them over time.
2. A spirit of a particular theme and/or emotions can merge with a soul bearing the same signatures. And though verbal consent is not needed, some part of the host must be willing to give the spirit that control.
3. A greater force such as a deity or witch placed them into the body.

These spirits are different than the other two due to the fact that as soon as they possess a host, they are connected to that host. Death to the host is death to the spirit.
