From the introduction: Far in the future, in a universe we thought devoid of life beyond Earth, we found a ring shaped space station populated by giants. We are insects to these creatures physically and mentally. Although humans that try and contact the Station Keepers almost always meet a swift end, we have been able to get into the bowels of the station. Literally the bowels. The station is part living organism, part technological and part unknowable. There are creatures we recognize as "Intelligent" that make up part of the station's system and many that cannot be reasoned with. On the station there are answers to any question you could imagine asking. Getting to those answers is the problem. They are guarded, cryptic and mysterious. Why would you enter the station? Are you looking to strike it rich stealing wondrous technology? Do you have a relative with an incurable disease that you hope to find a cure for somehow? Are you just insatiably curious and want to prove your theory for what the Station Keepers are doing? Everyone that comes here has their own reason. What will it cost you to fulfill your aspiration?
