While any mage who favours Dynamism may experience a form of madness in their Quiet, Marauders embody Dynamism; the real world is translated into their fractured version by a constant, subconscious use of vulgar magic.
Within the bubble of alternate reality that surrounds them, their hallucinations and bizarre rules are real; objects and creatures that come into contact with the bubble are transformed to fit in with its rules. They return to normal once the Marauder moves on, without any evidence of what happened, though the effects of conscious magic remain. Awakened mages and supernatural creatures who enter a Marauder's bubble may recognise that something is wrong, as may anyone who possesses some kind of supernatural awareness. The size and power of the Marauder's reality is directly related to the strength of their resonance, which is also dominantly Dynamic, though it may also have touches of Static and Entropic resonance.
The external Quiet of a Marauder protects them from Paradox; their alternate reality supports their paradigm, so the vulgar magic they use does not violate the rules of that reality. That does not mean they do not attract Paradox, only that most of the backlash is deflected onto other Awakened beings outside the Marauder's bubble.
While the nature of a Marauder's power may make them seem invincible, they are still severely hampered by their madness. They cannot become Archmages, as they lack sufficient insight and are incapable of appreciating truths which do not suit their madness.
Marauders are generally loners, though it is sometimes possible for a small group of them (called a "fusion") to share the same Quiet. There is also the infamous "Umbral Underground", a loose collection of Marauder terrorists who fight the forces of Static and Entropic reality. The most famous cell are the Butcher Street Regulars, famous for their acts of "zooterrorism". This group has grown weak since the Avatar Storm, cut off from their leaders and the mythical beasts they commonly interacted with in the Umbra. They are now led by the Regular's leader, Robert Davenport, a highly self-aware Marauder.
The most terrifying group, however, is the Chaioth ha-Quadesh. Formerly known as Bai Dai, these mages believe that it might be possible to restore the old days of free magic by eliminating several billion humans, making the consensus easier to manipulate. The disparate Bai Dai have been organised by a cabal called the Sitrin. They kill large numbers of people as often as possible. Like the Underground, they are divided into smaller groups whose members' Quiets generally agree with one another's. Chaioth ha-Quadesh generally have a static (Clarity) Quiet distinct from their permanent Quiet, into which they sometimes slip.
In the second edition, Marauders were much more cogent and likely to operate in groups, with the Umbral Underground using the Umbra to infiltrate any location and wreak havoc with the aid of bygones. They were also associated heavily with other perceived agents of Dynamism, particularly the Changing Breeds (who equate Dynamism with the Wyld) and sometimes Changelings. For example, the Marauders chapter in The Book of Madness is narrated by a Corax named Johnny Gore, who relates his experiences running with the Butcher Street Regulars.
In the Revised Edition, Marauders were made darker and less coherent, in keeping with the more serious treatment of madness used for Malkavians in Vampire: The Masquerade Revised Edition. The Avatar Storm was a very convenient explanation for the Underground's loss of power and influence, though they also became more vulnerable to Paradox. In this edition, the Regulars are a cell of the Underground, and like the other cells have highly compatible Quiets.
