Total Conversion Drive

The maneuver drive of Oerth, this theoretical drive converts reaction mass directly into energy, perhaps in the form of photons or gravity waves. The result is a fast drive that is highly efficient. Of course, a ship has to refuel once in a while, but sometimes the fuel is garbage. This drive just converts the fuel into energy and away you go. The engine is much more efficient than Spelljamming, so it's a feature on all of Oerth's metal ships.
