Chapter 1: the Infinite Realms of the Dead
The Ghost-Zone is the realm of the dead version of the sea created by the emotions and dreams of the mortals that die when it fuzes with all the different types of celestial magics. Which causes the ghost in the Ghost-Zone to be more powerful than their underworld counterparts.
The Ghost-Zone is what separates the different realms of the dead Hades, Vallahala, heaven, hell etc which are like floating island nations separated and protected by the magical barrier created from the mystical signatures of the different mythologies.
The Ghost-Zone has not had a true patron god since the age of pariah dark, because he was sealed by ancient ghosts who were actually various rulers of the underworld who banded together to stop pariah dark reign when he tried to take over the different realms of the dead.
The Ghost-Zone is endless and chaotic in that it is near impossible to navigate which is why it's near impossible to leave the ghostone once in it unless you happen to stumble upon a natural portal.
The reason that ghost avoid messing with natural ghost portals is due to the fact they are unstable and you never know where or when they will take you and you can never tell when the portal will close and when the ghost gets trapped outside of the Ghost-Zone long enough it will lose its ectoplasmic body and the soul will be collected by the death god that has claim in that region and the underworld kingdoms are a hell to the ghost that new the freedom and power provided by the Ghost-Zone.
The Ghost-Zone's original name is N'etherneir.
The inhabitants of the the Ghost-Zone are diverse in that you have the natives that are formed from the Ghost-Zone or you have the souls of the dead that got lost into the zone and got a second life or you have various monsters or mythological beings that got lost their and mutated into new creatures.
The Ghost-Zone is the biggest nation in the realm of the dead. However since it has no ruler the entire zone is protected by the treaty that was formed after the defeat of pariah dark as all the rulers agreed that if anyone tries to declare themselves king of the Ghost-Zone that it would be a declaration of war against every other nation in the realm of the dead.
The Observants were made by the seven god kings of the dead that defeated the ghost king as a way to ensure some semblance of control and to prevent the rise of the ghost king or the birth of a new one.
The Ghost-Zone is the only realm that does not have a mortal realm counterpart pantheon and as such none of the gods of earth are aware of its existence as the gods of the dead have hidden it from them.
The reality gauntlet was created to house the crown jewels of the crown of fire as no one could wear the crown of fire before pariah darks reign and were lost before he took the throne.
The seven kings that banded together were
Hades/ Pluto Greco-Roman god king of the dead
Hela Asgardian goddess queen of Hel and Niflheim
Osiris Egyptian god king of the underworld
Arawn Welsh god king of the underworld
Yomi Shinto god of the underworld
Supay the Quechua/ Aymara and Inca god of the underworld
Kanaloa the Polynesian god of the underworld
The Lovecraftian horror stories are based on the tales of people who accidentally went into the Ghost-Zone and came back mad. For mortals can not go into the Ghost-Zone for it will drive them mad.
The ghost zone is a 6 dimensional realm that the human mind cannot comprehend the only reason Sam and Tucker don't go mad is because Danny subconsciously shields their minds and they see the Ghost-Zone completely different then Danny does.
When Danny went into his parents untested ghost portal and turned it on it created huge pulse of ectoplasmic energy that covered everything with in a ten mile radius of Amity park thus not only turning Danny into a half ghost put also fusing him with everything that has the same ectoplasmic signature as Danny from the blast turning amity park into his lair/haunt and gives him the power to manipulate it into any way he desires.
The dead have their own language which sounds like a mixture of moaning tv static and incohesive under the breath muttering and when a living person hears it freaks them out cause they're minds can't process properly what they are hearing.
