Deep in the under dark, where the Dark Elves live, there lives all sorts of mythical beasts & ancient flora in the dark chasms.  Far beyond the suns reach is where the plant life takes on its own means of illumination.  the Fungi forests of Trilimac grow in the darkest reaches, giving off a fluorescent haze like magic energy pulsing from a wizards spell.

I wanted to re-create something similar to that in lamp form, so I picked the earthy colors of mossy green, charred browns and then a vibrant midnight blue.
