Another example of the Dragon Kings’ useful, everyday crystalline technology, a Library Crystal system takes the form of a small collection of 12-foot tall crystalline obelisks (the individual Library Crystals), and their attached terminals, which resemble 5-foot pillars with large reading crystals implanted at chest height. The spires, 3 feet wide at the base, and their terminals are placed in a particular radial arrangement, creating the effect of a grove of gently shimmering crystal.

On their own, a Library Crystal system is merely an improvement over the smaller and more mobile Reading Crystals, capable of containing within itself vast amounts of knowledge. Each spire is capable of holding an entire genre or section of written works or images; a system of them, essentially, is an entire library of knowledge, hence their name. This knowledge can be added to and accessed from the crystalline terminals connected to the tall spires.

However, when powered with additional essence from essence-users or Hearthstones, a Library Crystal system reaches out to attune itself to all Reading Crystals within range, allowing those Crystals to access information stored within the library and display it to their users.

In the First Age and before, all Dragon King settlements of any size possessed one of these exceedingly useful systems, allowing their residents’ lives to be improved by easy access to lore, fiction and even visual art. Today, however, many of these useful devices have been lost, destroyed either by the passage of years or by those who seek to limit easy access to information. Of those that still function, their hearthstones have been stolen, and the librarians who tended them are dead and gone; they sit forgotten, dull, cracked, covered in vegetation or dust… but still contain vast knowledge from the First Age, ancient lore that, in the barbaric Age of Sorrows, is priceless.
