He wears a cloak of invisible voices, wove from the frequency of silent screams. Ruler of the space between waking and dreams; He is the Yellow King.
Fear not what you can't remember, though His kingdom is obscene: A place of waste and decadence trapped beneath perception, sewn with hidden seams.
He takes his toll, unbeknownst, at the liminal space between asleep and awake; collecting your soul, bit by bit, inch by inch, until there's nothing left to take.
