The Neso Triangle was a regional anomaly (today's jump point to Croshaw) near the orbit of Pluto. It was known for the disappearance of the Goodman and two other ships in 2262. It was officially declared a no-fly zone by the government in the same year.
Discovery of the jump point
10 years later, Nick Croshaw discovered that the anomaly was a wormhole, connecting two low visible gravity-wells through a tunnel and was able to fly through the anomaly. It was found that more of these anomalies existed and they were called jump points.
