Rogue Trader - The Hos Dynasty
Shards from Magoros. Will only change their colour when exposed to light
These are fragments recovered from the Egarian ruins found in the Magoros system, both from the Maze City and the Memory Archive within. Dull, slightly opaque crystals they produce a variety of colours when light is shone into them in a method that defies prediction by the Adeptus Mechanicus. Like all Egarian technology, their true function and method of operation remains unknown.
