The Grayson Yard was the main shipyard in orbit of the planet Grayson in the Yeltsin's Star System. In 1903 PD, the damaged HMS Troubadour was brought to the shipyard to be repaired, but due to technology differences between Grayson and the Star Kingdom of Manticore, the alpha nodes could not be replaced, while the beta nodes were moderately repaired.
