Core



A core is a special object that can only be sensed in the main ghost world. It has the appearance of a white orb with an aura of another color. Only Temsik souls have the ability to inhabit one or more cores (depending on their type of Temsik abilities) and perform a specific action with the containers of the cores.

Criteria
There is a specific criteria for a core to exist within an object:
 * The object must be capable of voluntary motion or linked (not necessarily in the sense of physically connected) to something capable of voluntary motion. This means that if the object in question is only capable of motion with help from forces such as gravity, it will most likely not have a core; however, special instances, such as water drops, may have a core regardless.
 * The object must be able to interact with another.

Importance of color
The color aura a core has determines different factors. The following is a list of all core colors:
 * Blue: A blue core is the "normal" core because it doesn't change any factors related to inhabiting.
 * Blue (flame-like aura): A blue core with a flame-like aura is a core that belongs to a Temsik soul. Unable to be inhabited, only talked to.
 * Red: This red core is able to be inhabited, but only for a short while, as the container will force the Temsik soul inhabiting it out of its core anyway.
 * Yellow: A yellow core belongs to a dead body.
 * Green: A green core is mostly able to be inhabited, but manipulative abilities become limited.
 * Purple: A purple core is unable to be inhabited.
