The Cause is a group of allied organizations secretly working to oppose the Principality invasion and occupation of Palisade. The Millennium Break side of the cause is commanded by Gucci Garantine. Each of the factions is named after a color and a water feature due to Gucci's naming sense.
Factions
Blue Channel
The faction composed of the Blue Channel's crew. Supported by some Twill people.
Jade Kill
A military faction which "opposes with direct assaults and force", based in Joyous Guard. Jade Kill is led by August Righteousness and his Delegate liberation group, Reunion, "and supported by Kalar Anakalar's Giantkiller unit and a wing of Swordbreakers."
Violet Cove
A strange faction which "opposes with the weird and unexplained", based in the Isle of the Broken Key. They have a "battered and corrupted backup of Crystal Palace's final predictions for the future" in the form of somewhat obtuse prophecies. They have allied with the cult of Devotion because it was predicted that they did so in their sacred text.
Grey Pond
A group of suppliers which "opposes with new equipment or supplies", based out of the hills of Sinder Karst. They are "blue collar revolutionaries" from the Oxblood Clan, the Company of the Spade, and the Concrete Front.
Carmine Bight
A group of adventurers which "opposes with bold action and unpredictable tactics", based out of Rifle Island. They are submarine pilots and submarine pirates, long descendants of the Herringbone Flotilla and Lineage Brighton. Carmine Bight is led by Captain Skelton Knaggs and "guided by a coalition of Hyphan navigators".
Rose River
A research unit which "opposes with ingenuity and curiosity", based out of New Oath. This faction contains not only Veronique, Fealty and their supporters, but an NEH Sleep Detachment squad from over 5,000 years ago. Lonny and T from the Twilight Mirage "godspeed, glory" episode descriptions are members. The group is melancholy and dreamlike, and they "hope for a day when they can be something other than soldiers."
