A closely guarded secret of the Star Gods, this sophisticated device is able to read, write and erase the contents of one's mind. The Stellar Empire uses it for intelligence purposes, as well as to imprint skills, knowledge and loyalty upon their freshly-bred clone soldiers.
However, the Scanner has its limitations. Every mind, especially a natural-grown one, has its unique internal language of great complexity, making any deeper tampering difficult, imperfect and damaging.
The much less potent, portable version of the Scanner is known as the Mind Probe.
