Founded by legendary Nar Shaddaa gangster Cayce Urriah, Walkers in Darkess is the largest and most active of the Black Sun Syndicate franchises.
Walkers in Darkess divides its activities between smuggling operations and Syndicate criminal activies, such as slicing, extortion, bribery, "protection" and strong-arming.
Smuggling activites are managed by Captain Tesserian whose spice fleet travels the known galaxy in search of trade.
The criminal division is run by Klugga the Hutt from Klugga's Palace in Mos Espa.
The Black Sun is currently experiencing a split between Klugga and Tesserian over the focus of the Syndicate, with Klugga pushing the Syndicate to become more powerful in the galactic south, while Tesserian has increasingly aligned the Black Sun with anti-imperial forces in the galactic north, along trade lines running from Ord Mantell to Mon Calamari and encompassing the Perlemian Trade route.
Klugga has recently launched an initiative called The Dark Trade Federation, ambitiously aiming to control all galactic trade and criminal activity, while Captain Tesserian continues work to divert food and fuel supplies from Coruscant through a series of trade deals, and by supporting piracy and commerce raiders.
The Walkers in Darkness eventually disbanded when Cayce left the syndicate to serve her people, the Mandalorians, and Klugga apparently passed on, having died in his home of publicly unknown causes.
