The Handbook

A book created by the legendary tattoo hacker Kairo, detailing his experiments into creating a Nanocel Assemblage to mimic the structure of a human brain. He calls this hypothetical construct a swarm, and some people believe that he managed to create a swarm complex enough to transfer his own consciousness into. However, for most people this is in the realm of mythology, and the Handbook remains a hypothetical text on ways which could be used to add more computational power to a tattoo.

The most common practical use of the Handbook, therefore, is its appendices. These list a number of mechanisms for using one nanocel to affect another's structure, including formulae for the assemblages used to program tattoos, as well as a vast list (appendix VII) of common poisons.
