Mushroomglow
As there is no sun below the ground, day and night are not experienced in Subterra in exactly the same way as they are on the Surface. Instead, those who live there experience a roughly corresponding cycle known as Mushroomglow and Dimming.
Manifestation
As the sun rises over the horizon on the Surface, the prolific and varied fungi that flourish in Subterra begin to glow with multicoloured bioluminescence. These fungi are cultivated by the denizens of Subterra to provide natural light on roads and in cities that roughly follows the day/night cycle experienced on the Surface.
