The Lower Dark

The Lower Dark has always been a strange, creepy, and dangerous place within the world of Dephiron. This level of the underdark extends from 10 miles below the surface to unfathomable depths and features a degree of strangeness that would drive the surface dwellers insane. Few upper-worlders ever descend to the Lowerdark, and few of the Lowerdark's denizens want anything to do with the surface world. Some of these creatures in the Lowerdark intelligent or otherwise aren't even aware of a surface world; others have heard of it but consider it a mythical place.

Some races within the Lowerdark have lived here for generations upon generations, and the Lowerdark is considered there home despite them being intelligent creatures or having common sense. Other creatures settle here to take advantage of the Lowerdark's unique magical properties, rare ores, or shelter from the much hated surface. Many view the Lowerdark as a temporary solution to the dead magic zones, and hostile territory, and as a means to escape the law from both the other Underdark layers and the surface as some dangerous criminals dwell in the Underdark. Not everyone is in the Lowerdark by choice, as some unfortunates are here because they neglected to research the destinations of the portals through which they ventured. Others have been exiled here from communities in the Middledark, the Upperdark, or even the surface world. Some of the higher up drows tend to send their potentially problematic subordinates to the Lowerdark on missions to correct them but most likely kill them. Several Middledark creatuers and races make their way into the Lowerdark, some for expansionistic desires, others for resources, few because they have something to prove, while those chosen by entities to protect the secrets hidden down there.

In the Lowerdark the most dangerous are sealed and many are left in eternal slumber. Should these entities awaken would result in the destruction of Dephiron. This is where the darker gods, forgotten gods, the unknown beings, and even some of the Forsaken gods are sealed away. Specific Slayers are chosen to venture down into the Lowerdark and are stationed there for majority of their life to ensure that these things are not unsealed as it would mean the end of Dephiron and perhaps a new era will emerge.

Cosmic Invasion Effects
Following the Cosmic invasion the Lowerdark has gotten stranger and near uninhabitable to other creatures and many Slayers had to venture out of the Lowerdark. The realities are warped and those that venture all the way down will experience their own type of powerful reality warping hallucinations as most will be expected to confront their own fears and nightmares. Those that travel down there and eventually return if they are lucky never fully recover as scars are left on their psyche and many are unable to un-see what they saw down there. Many Slayers who managed to get out of there reported back to their respective guilds that the Mind Flayers have been more active and that they are potentially rebuilding their once lost Empire again however those that attempt to stop them and venture down there never return presumably becoming Mad Slayers. In the lowerdark realities began to bend as well as realities from different planes creating rifts and travel between other planes.
