Cyber Elf
A computer life form generally unknown to humans.
Commonly referring to a repliroid's will, consciousness, personality, etc.
While many scientists continue to study the repliroid mind for answers, the current concept is generally acknowledged as not a program itself but the "volition of a bodiless life form."
Though cyber elves are invisible, repliroids are able to see (or sense) them.
In the field of research focused on the activity of the mysterious computer virus the "Sigma Virus" on the repliroid thought program, it was proven that the virus possessed an effect of "volition."
That "volition" became known as a Cyber Elf, and additionally any such volition that had the ability to influence things in a similar manner (Sigma Virus included) became designated Cyber Elves.
The study resulted in reached the level where it became possible to strengthen a repliroid by means of a cyber elf.
