Transitory creatures stuck in limbo. An aspect of the story that the next journal writer may speak of briefly, but definitely a larger part of other character's stories. Some I haven't introduced yet, another being Maikori as she is a Spectral Being herself.

The Oneironaut: Creature from a dream-cult hellbent on seeking Fairyhood through endless sleep. The asylum provided just the tools for the fatal dose...
The Gravetender: A hulking brute who limps across the poison swamps, weighed down by tragic burden; gifting flowers to the dead.
The Guardian: A peaceful, but aggressively territorial serpentine spirit. Guards a door of unknown import, hoping it will one day open - from the inside.
The Ballerina: Dancing frigid tears of longing for a lost friend.
The Watcher: Feigns an ancient crown. Ever watching through eyes of shattered glass. Surely, it has swallowed what lay beneath.
The Maiden: Forever adrift in the sea of her mind - her love will never set sail.
The Vessel: Ensnared by shackles of roots - warped further and further by trying to quell his feeling of unrequited love.
The Prowler: Twisted beast who stalks the Hollows. One of the many, as the Hollows welcome all manner of menacing Spectrals and beasts.
The Gentleman: Shambling along to a forgotten number, but the show must go on.

Seemingly impossible to comprehend, even for a Fairy.
