The Deck is a criminal enterprise in the in-universe equivalent of the United Kingdom which has a major presence in the region around Southden. They have been tied to several blackmailing scandals of politicians, and are also involved with drug smuggling, cyber crimes, and underground fighting. Their only currently known front is an underground fighting ring that operates out of a disused Underground tunnel in the Southden subterranean commercial district.
Jane and the crew initially go to The Deck for help with acquiring identification cards for themselves, and vehicle registration for their motorcycle. Later, Fuse does some work hacking into a government database in exchange for several computers and an apartment that could be used as a base of operations to stop one of Patton Thale's plans. The Deck also helps Jane's group purchase all of the property in Ilworth.
Members of the gang adopt aliases based on Tarot cards. It is currently unknown how many members of the gang there are in total. Jane has met two in person, and knows of one other member.
