Conversion Field: Strange crystal growths and uninsulated gold and copper wires have appeared on the device, which resembles a small telescope. When turned on, the field emanates from the parabolic reflector lens at the larger terminus. Through the corruption of aeons and a long lost process of ancient physick, the field transforms incoming kinetic energy into multicoloured hues reminiscent of warpfire. When the conversion field is activated the crystals internally mirror the hues produced. Blue sparks surround the exposed wiring when the device is overloaded (which is often) and continue to arc until it is fixed. Sometimes a viewer can see the likenesses of people he knew long ago in the light the field projects.
This conversion field is one of the ancient marvels built in the great forges of Jupiter, the Mark I Jupiter Class conversion field. Its Galilean moons produced breathtaking works of technology even through the Horus Heresy, although both sides of that conflict were served; that war divided even the Jovian tech-priests and their shipyards. Conversion fields have a storied history, both fair and foul, their might having been exemplified by the treacherous High Lord Goge Vandire and steadfast Inquisitor Lords. This field is of the fabled Jovian Mark I make and it may be the last of that class existing in the galaxy at the end of the 41st millennium.
