Kingdom of the Sunken Sun
A kingdom where the sun has vanished from the sky, plunging the world into eternal twilight. The inhabitants have adapted to the darkness; their eyes can see in absolute blackness, and the streets are lit by crystals that hold the last remnants of sunlight. In this world, a cult called the Lunar Brotherhood worships shards of an ancient moon that fell to the earth. Beneath the surface, underwater cities are home to intelligent beings whose skin shimmers with deep ocean hues.
