The Lantern King

The Lantern King is one of the Eldest, a divine fey creature of tremendous power said to be able to reshape the very fabric of the world on a whim. He is known for his capacity as a trickster god mixing caprice and mischief in god-like capacity within a realm already full of such practice. His sense of humor is vast, both in its breadth and its potential for harm, and his pranks, even well-intentioned ones, are not always pleasant or convenient. However, those that have spent a long time in his presence note that behind the Lantern King's mischief is a cunning, cosmic-level schemer influencing numerous major events across the Great Beyond.
The Lantern King resembles a foot-wide ball of golden light surrounded by a circlet made out of glyphs. When expressing a point or emotion, he often changes color. Because of this resemblance, he is sometimes suspected to be the progenitor of will-o'-wisps or the original model for lantern archons, but the fey lord derisively laughs off such claims. He is the father to the "Five Storms" and is said taught them how to manipulate mortals and turn them against each other. No one knows how he feels about his children being sealed away. If anyone brings the topic up he seems to not understand the question. He speaks in a booming, merry baritone which is the only indicator of his gender. The Lantern King is also capable of taking the forms of other creatures, including other Eldest, to cause mischief.
The Lantern King has no permanent abode. He wanders freely through the fields and forests of the Feywild, bending reality and changing lives wherever he goes, and is often blamed when a traveller is led astray. He is particularly fond of the Witchmarket, a caravan that travels across the Feywild and into the Material Plane.
