Maybe this is extremely obvious, but recently it hit me that The Dark Legion forces can be viewed as anti-corporations. In other words, that each corporation has an opposing Dark Legion Apostle.
If we look at a Dark Legion aspect, we can usually find a Corporation whose ideals are a close-to-exact opposites.
In particular, Ilian is the Mistress of the Void, and her power is drawn from the knowledge of the Dark Symetry (aka Magic). The opposite of that would be Technology (Science vs Superstition) ... which is the ideals of the Cybertronic Corporation.
Algeroth is the Lord of Dark Technology and War (War in particular). His opposing Corporation would need to be one that avoids War. In particular, Capital is described as a corporation that regards War as a last resort ... their military forces are structured in a primarily defensive nature ... and they prefer to "buy" other corporations/holdings instead of taking them by force.
Semai is the Lord of Lies and Deceit. Mishima is the Corporation which personifies Honor and Fealty to one's Lord.
Demonginous (sp?) is the Lord of Decay and Pestilence. Imperial is a corporation which (for lack of a better word) exemplifies Vitality. This can be seen in how they are always exploring new lands (ie Conquisidors) and their relatively colorful troop types (Wolfbanes).
That leaves Muhjawan (sp?) and Bauhaus. Muhajawan is Madness and Anarchy personfied. Bauhaus society is all about structure, law, and reliability (or at least from the flavor text it is).
Now can the opposite case be made (that each Corporation has a "similiar" Dark Legion Aspect). Algeroth and Cybertronic (Technology) Muhjawan and Imperial (Imperial troops (Wolfbanes, Mourning Wolves, etc.) don't seem quite "right" in the head). Ilian and Bauhaus (The Symetry and structure) Semai and Capital (Greed and Envy drives them both) Demoginous and Mishima (hmmm ....)
