The IRS Medusa is a gravitational inversion rig in service with the Western Armada of the Imperial Navy of Shireroth since 1643 Ab Nortone. It is the latest iteration of the long-running Project Mortis an enduring attempt by Shireroth as well as, formerly, the Kingdom of Babkha and an independent Elwynn to reverse engineer and replicate the anti-gravity technology of Jasonia and Menelmacar.
The Medusa incorporates significant amounts of software lifted from the Babkhano-Elwynnese Panopticon programme, a suite of electronic hardware and programs designed to achieve total information awareness over the battlefield, although the Babkhans invariably abused the programme to create a system of domestic mass-surveillance.
