TransEarth
When the power for humankind to step into a identical world was first discovered, people had different approaches to it. Some said that it was a sign of the incoming apocalypse, others that it was an unnatural thing and should be shunned. The Black Corporation, however, believed that it was an easy way of getting money quickly and easily, and so transEarth was born- a company trying to extract as much wealth as possible from the alternate realities. It is part-owned by Douglas Black and Lobsang.
