Deep underground in the Black Wood, there is are long networks of cities, collapsed underground. They were among the first cities created by the Golden Elves from on high on the surface, long ago. In these cities, they engineered the Silver Elves in their likeness, and also created the Terran as well. The Silver Elves were ripped out of Time and Space in strange experiments to test their strength and endurance. So cynical were their masters in their decadent latter days, that they performed many unspeakable evils in projects conducted in these cities. These evils later became buried underground, as horrible monsters of experiments gone awry, or as ancient, buried artifacts of power. They raised the Silver Elves in their own likeness, In these cities, powerful and mighty technology was wrought, and many ancient mysteries. They were the first to power their cities with spilt up starlight, which they also used to inform their own archetypes.

Some disappeared from the surface long ago in a War waged with apocalyptic weapons. Others were buried over thousands of years, as the aggressive mega trees covered the forest floor in their detritus, as thousands of years of branches died off and fell to the ground. The rapidly evolving underground life also repurposed the cities for their own use as well.

There was a strange, insulated effect on the ground that came out of these bunches of detritus. It was a maze of dead vegetation and large branches in various states of decay all over the forest floor. Having a watchful touch was a necessary adaptation, leaving the creatures that still survived from the quickly over growing forest to develop a an extremely refined sense of touch that

Accessible by ancient tunnels, which were formerly a protected highway system in ancient times, was the Old Capital of Lux. These tunnels themselves were a large complex of ruins. They stretched through large underground lakes and rivers. One is the large underground rivers of Naib. Life forms utterly strange live in these subterranean depths, guided by a sense of touch.

Because of the horrors that occur underground, a group of Silver Elves split off, and were sundered into the North, building holy cities in the highest mountains to get closer to their circumstances.

Nowadays, a Citadel City is built on top of it, but Lux can be accessed via numerous trapdoors and sewer tunnels under the city. Underneath is a mesh of a very large labyrinthine series of tunnels, twice entombed tombs and ruins of former residences, shops, and temples.

Some parts of these cities became horrible experimental zones. Many people, carefully selected as a population zone, were kept in these dark circumstances, but given certain advantages. This ended with the creation of orcs.

But it’s most extreme feature is its utter blackness of its depths. No light finds its way down into its frigid depths. Lux used to be a city of Technicity, or a city in which many of the needs of the Ancient Elves were met by means of an Advanced Administrative AI, powered by reincarnations of the Ancestors.

Because of these strange environments, the cities that are long sunken are populated with many ancient, buried artifacts. These hold immense power, sitting in abandoned buildings. Liches, rats, vampire clans, and necromancers all take refuge from the prying eyes of civilization by going underground and unearthing artifacts of power. Old alchemical laboratories, and times of cobwebbed thaumaturgical libraries, with books long since ruined, sit in the dark.

The evil that lays under the civilization extends even to the trees. The tree roots extend down in an ugly network of writhing hostility.

At the top of Lux, sits an old Castle, known as the Fortress of Solitude. In olden days, it was built in a classic style, emphasizing the wide, cavernous spaces that expanded upward. In older times, after the False Dark Lord took over, this cavernous space gave extra expanse to the darkness. Inside the spaces of the old castle lay faded finery of silver and gold, having not seen the light for so long, and riddled with bacterial pestilence.

Living Gargoyles guard over the space from the other denizens of Lux. The hunter glimmer of the moonstone and ruby their bodies are carved from gives a smooth elegance to their heavy, cold forms.

And in this deep darkness, their slumber old evils, waiting to wake...
