"Something happened. No one knows how or why, but Humanity was granted a gift. Among the stars, with little hope left for our kind, there came to be EXAULTED. Humans with extraordinary powers that manifested seemingly at random. We prospered with newfound energy and determination we had not known for centuries. We spread farther across the vastness of space, expanding at an ever-increasing pace. Nothing stood in our way. Not until SIN."
