There are several ghost types on this world. Each differnt spirit or spector comes from a different time in the world's history. But, they all faced their end at one of any number of cataclysm. The most recent cataclysm was the Grand Sundering, where the floating forest was ripped from the land and formed the Grand Scar. This event also had the unintended effect of causing massive spiritual anguish. Almost every ghost, spirit, or specter was affected by this and turned mad. Now they roam their graves with furious territoriality.
@The Mad Mage - Once the Immortal King of Solace. It was he who ultimately cause the Grand Sundering. This action caused the destruction of his kingdom and the deaths of all who followed him. He now roams the Petrified Wastes and fiercely protects his final resting place.
@Ash-King - Once a Prince of Solace. His rebellion spurred the Mad King into action, ultimately responding with the Grand Sundering. The Ash King, failed in his attempt to take the source for his own-returned to exile in his madness. He roams Luna Mountain. Once a friend to friendly forest sprites. He now leads a small army of angry sprites, furious their forest is long since gone.
Ghosts of @The Gloomwood Mire - The survivors of the Grand Sundering where left in a world without fresh water, as the Grand Sundering had drained the oceans. These survivors traveled west following the path of the remaining rivers as they dried up. When these survivors came to Gloomwood they found the last remnants of water, now fetid, stagnant, and stale. The spirits who remain lament their fates most of all.
@Lydia's Ghost - The only ghost to remain largely unaffected by the psychic devestation of the grand sundering. Lydia maintains vigil at her monument, far to the north. She is the only creature besides the Fae-Wyrm that can remember the history of the world, the cataclysm and forming of the @Floating Forest, and the location and threat posed by the @Lavos Remains. If the party has @Schala's Pendant or has @Schala in the party Lydia will be able to generate a portal that brings the party directly to @The World Core.
