"Science fiction is what scientists would do if they could - if they had enough grant money, enough time, and enough brains to do the wonderful things they would like to do."
- Greg Bear

Black square  
  A device for secret communication.  

On Anteac's lap lay a small square of inky black about 10 mm on a side and no more than 3 mm thick. She wrote upon the square with a glittering needle, one word upon another, all of them absorbed into the Square. The completed message would be impressed upon the nerve receptors of an acolyte messengers eyes, latent there until they could be replayed at the Chapter House.
