The Earth is an untamed wilderness, unrecognizable from centuries ago when humanity enjoyed a Golden Age of peace, abundance, science, and art. This era of enlightenment was brought about by the discovery of new global teleportation technology known as Gates. The end of human society was similarly brought on decades later by the sudden and catastrophic malfunction of this technology, when control of it was lost and the Gates opened random doorways through space-time. These permanent, uncontrolled rips in the fabric of the universe are known as Breaches. Through them pour alien beings, creatures, vegetation, plagues, and environments. The Earth was transformed in an instant, and human civilization collapsed in an event now known as The Fall. Very little verifiable information exists from the centuries that span from The Fall until only a few generations ago. The Breaches are still open and active, but humans normally avoid them, preferring to steer clear of the dangers they present. For alien beings or creatures that pass through, it’s a one-way ticket; Breaches seem to all lead into our world, but not back out again. Anything that crosses into our world is permanently made a part of it, to live or die on our dimensional shores.
