IS-Free is a completely documented and explored space, and it boasts the record of the only space to be so. Being a mere volume of around 6,000 kilometers it also boasts the simple structure. IS-Free resembles an ancient library with many physical books but also a cache of digital storage which has illuminated almost nothing. None of the data is comprehensible and neither are the books, not only is it written in an esoteric language, but even when both decoded and translated it still just rambles, making no sense of anything at any point and is completely devoid of any intrigue or value and much of the data as the books simply end.
