Villains and Blackguards Incorporated (VABI) is an organization found on Earth 32aa which has dedicated itself to protecting the interest of those of differently enabled morality and enhanced humanity. They take care of legal expenses and investments. It has become a very successful organization and is considering spreading to other Earths. In case they do here are some of it's members.
Travelling between realities is difficult. Quantum mechanics make it seems simple as first. The idea that if a particle is given two "choices" then the universe splits and two and the particle does choice A in universe 1 and choice B in unverse 2.
If only it were that easy.
In point of fact, reality acts as a kind of gravity, or rather there is a conservation of reality. If the choices given are so small as to make no real difference then one of the universe collapses back into the quantum foam. A universe with a very strong reality creates such a void of this quantum foam that it takes incredible energy to reach a reality that is different enough to be its own.
Many of these realities fall into the sway of the conservation of reality of the prime reality. They are shadows that only gain "realness" when pumped full of energy. Generally it is not worth it unless you are mining for a specific artifact or person. Some have used these shadows as prisons. Pump them full of energy put the a person in there and let the energy run out and the reality fade again to shadow. VABI considers this very cruel and needs a 2/3 vote of all divisions to do so.
Beyond that there are an infinite number of earths. We use the Wehler/Gharm/Metoff system of position multidimensional structures for navigation which is why we are designated Earth 32aa. You can look at the PDF to understand how it works.
We get to these earths through various means. The best is the Evocation Site. A point on our earth in perfect alignment with a super string that cross contaminates several realities it can be boosted with raw power to form a "road" of sorts. Perhaps not the most comfortable means of travel, but it is very safe.
