Through the MAW
Yuri’s Jaunt was a cargo starship found derelict in the asteroid fields of the Gehenn System following the formation of the Triumvirate. It appears to have run into an asteroid causing near castrophic failure with all hands lost. It was an important discovery due to its intact MAW drive. It’s theorized that since the ship was effectively dead during ETP‘s spread and Abbadon’s Cry that it missed both events. Scientists were able to retroengineer current MAW drives based on the one found in Yuri’s Jaunt.
The ship has been made into a monument, being permanently affixed to the asteroid it was found on.
