Cayden James's criminal cabal

Cayden James leads a criminal cabal consisting of Laurel Lance, Ricardo Diaz, Anatoly Knyazev and formerly Sheck and Vincent Sobel. Their goals are connected to revenge on Team Arrow, with Cayden James specifically declaring his intent to build a thermonuclear bomb to destroy Star City in order to get revenge on Oliver Queen for the death of James' son, Owen Post.

Overview
The group united funds and forces of several criminal organizations such as Cayden James's Helix, Ricardo Diaz's drug ring, Anatoly Knyazev's "exiled" branch of Bratva and Black Siren's group. Thus, Cayden James was able to find muscle and funding for his elaborate plans, something his own organization of hackers could not provide. All leaders and organizations had grudges with the members of Team Arrow, be it Green Arrow, Spartan or Black Canary.

History
The group leaders were seen gathering together for the first time after the split-up of Team Arrow in late 2017, although Vincent Sobel hinted that their plans may have been in the works for some time prior to that. Black Siren and Cayden James have revealed that they had been filming what was happening in the Arrowcave since her infiltration there back in autumn. Ricardo Diaz and Anatoly Knyazev remained skeptical regarding the plan to divide Team Arrow, considering it not that impressive after all. Cayden James immediately calmed their concerns, saying that he has much grand designs for their revenge on Green Arrow.
