Roman Reigns has been directly or indirectly responsible for many feuds recently. In an old video, Roman claimed that everything in WWE revolves around him, which could be true. Some of the top stars like CM Punk, Cody Rhodes, Seth Rollins, Jey Uso, Kevin Owens, Randy Orton, Drew McIntyre, and others' story revolve around Roman and his actions.
Roman's story in itself revolves around him. Attacking the Fiend at Summerslam 2020 changed WWE's future for good. Since he turned heel, many stars joined the Bloodline like Usos, Solo Sikoa, and Sami Zayn. After his loss to Cody ar WrestleMania XL, Solo formed Bloodline 2.0 which has also been a result of Roman's failure to be a 'strong' Tribal Chief.
CM Punk threw himself into the Bloodline Civil War story as per the request from the Wiseman at the Survivor Series War Games. Roman might indirectly owe him a favor. Jey and Sami were forced to rejoin the old Bloodline as Roman's feud with Solo cost him the IC title.
