Only found in huge geodes; rocks on the outside with crystal-like quartz on the inside. The rarest and most precious of these geodes are those that contain the dark green zydrine within. Very rare and very expensive.
May be obtained by reprocessing Bistot ore and its variations which are available in null security status and wormhole systems.
Significant amounts of Zydrine are also present in rare ores like Spodumain and Rakovene.
