Located in the Skrell-owned Vir system‚ right on the edge of Frontier space‚ Virgo 3b is relatively unimportant on the galactic scale․ Purchased by NanoTrasen near the end of the Phoron War‚ Virgo 3b is a moon orbiting the gas giant Virgo 3b․ Notable for its atmosphere‚ which is composed almost entirely of gaseous phoron‚ Virgo 3b was originally utilized by NanoTrasen as a research black site and covert refueling station․ Plans to construct a space elevator were funded without question‚ revealing just how valuable NanoTrasen considered the asset to be․ Designed to ferry phoron gas up‚ and supplies and personnel back down‚ the Tether Facility never expanded to its full industrial scale․ NanoTrasen maintains the facility - and its adjacent colony - to this day․ Even though access to Phoron is no longer heavily restricted‚ NanoTrasen remains at the forefront of the field‚ and Virgo 3b provides the company with a virtually limitless supply of research material․
