Nova Crystals are an item that was, at one point, controlled by The Krath Dynasty, a faction in SWC. Some players and factions will accept Nova Crystals as an alternative form of currency to the credit in trades, however the SWC server will not accept them as payment for server based activities (such as Construction, Prospecting etc).
What Are They?
Nova Crystals are produced like any other object, through factories and manufacturing, requiring Nova in order to make them. These crystals have an equivalent credit value which the faction defines and will readjust on a regular basis. Players may accumulate several of them and opt to trade these with others instead of credits.
