Shadowless

Shadowless is similar to the Underdark, though the idea that all underground inhabitants are evil is completely outdated. It’s called Shadowless due to the absence of light down there and even magical light tries to illuminate it, the shadows are much deeper than you would expect. It is deadly, with many things being out to kill you by nature, with survival being your key goal. It makes the inhabitants feel quite neutral or selfish in outlook, as who has time to plot evil deeds when you might be fighting for your life the next moment?

In the upper Shadowless are bartering towns, where trade between the denizens of the surface and the Shadowless can come together to do business. Due to the dangers that are constantly lurking, waiting to take a bite out of those who aren't prepared, survival is key here (meat grinder rules apply, 15 or more to pass a death save).

Haggle
Deep below the surface lies the ruins of a Deep Gnome City and whilst much of the city remains in ruin, some sections now house small bastions of trade where Brights (surface-dwellers) and Shadowless (inhabitants of the underdark) can meet. One such enclave is Haggle; a lawless sanctuary in an even more dangerous set of ruins.

Haggle is about two days travel from the surface. These exits from the Shadowless lead to the mountains just south of The Dredges...

The Final Rest
A tavern/waystation run by a brother & sister duo of Shadar-kai, with an obnoxious goblin called Gurt as barkeep
