The so-called “silver world” of the Lorgans is strictly speaking a rocky planet with an unusually high concentration of silver and aluminum. Thus the planet shimmers as if it were made of pure silver.
The Lorgans operate a flourishing mining company there with its own self-government and laws. Despite its unusual composition, everything seems to be of natural origin. More exact investigations were impossible so far because the Lorgans do not tolerate visitors from other worlds there.
