Pyke approached Darth Maul on Zanbar at the new Death Watchcamp and he stated that he knew that Maul was forming an army. He then said that he had no desire to oppose Maul in any way and that he wanted to join the Shadow Collective.
Pyke and the Pyke Syndicate forces were instrumental in the eventual takeover of Sundari, the New Mandaloriancapitalcity, sometime after he joined Maul's criminal organization.
Pyke was a part of a small team that included Savage Opress that attacked and destroyed the Mandalore Banking Center. Pyke's team was ultimately "stopped" by Pre Vizsla himself, and Pyke and Opress were presented to the people of Sundari as prisoners.
