The Cyklo market functioned as a marketplace for slaves located on the planetary surface of Chalcedon. In the time of the Imperial Era, the Black Sun slavemonger, a criminal element, brokered a deal involving the Smuggler's Guide with the Varcinius Auction and Artifact Collective at this location.
The Cyklo market initially appeared in Star Wars: Smuggler's Guide, a reference work authored by Daniel Wallace that was published in 2018.
