Ghost world

The ghost world is a world separate from the main timeline and universe, inhabited only by wandering souls and souls whose death involved the Temsik meteorite coming into contact with their body.

Main uses
Temsik souls are able to voluntarily access the main ghost world, an exact duplicate of the main timeline and universe. However, in the main ghost world, time does not exist. As such, everything except souls is suspended in motion.

When a Temsik soul touches another soul's core in the main ghost world, they form a "connection"; from here, they can either break the connection or send themselves and the connected soul to an "alternate ghost world" of sorts. It is possible for more than two souls to be in the alternate ghost world. In this situation, all souls are able to talk to each other telepathically. As such, both thoughts and conversation are understood by all souls.

Other uses
In the main ghost world, if a Temsik soul touches the core of a dead body's which has not been affected by the Temsik meteorite, they form a connection and are able to break the connection or send themselves and the soul that belongs to the dead body's to the alternate ghost world. This certain situation is special because from the alternate ghost world, the Temsik soul is able to reverse the time to around 4 minutes before the death and prevent it from happening; however, only certain Temsik souls have this added ability.
