@SCNCY - Son of Dathomir is the 4 issue arc. Last of the Dark Horse comics (before the switch to Marvel), but I believe it is still cannon unlike many of its Dark Horse siblings. Maul unites Mandalore Death Watch, Pyke Syndicate, Hutts, and Black Sun together under the Shadow Collective name to battle Sidious/Dooku. Crimson Dawn is not a thing yet in this arc, so it appears Maul may create that group after this story goes down.
