Psuedo-gravity Drive
Psuedo-gravity drive - or PGD - is a loose term used by the Iluvauromeni to describe their first generation efforts to produce a working, viable anti-gravity system.
Almost nothing is publically known of how these devices work, although it seems likely that information gained from Menelmacar provided the spark which began such research inside Iluvauromen.
