The Techno-Mage (Babylon 5)
The technology the techno-mages use consists of bio-technological implants. The process of installing the implants and adjusting to them is excruciatingly painful. The presence of these implants means that techno-mages are effectively cyborgs.
A techno-mage may choose to establish a "place of power" for themselves, such as a particular planet. In doing so, they develop a strong connection with that place, and to some extent, a dependency on that connection.
Every techno-mage was taught and sponsored by an older techno-mage, being fully initiated after a long period of apprenticeship. The two most common ways of gaining an apprentice are simply by having a child or by adopting children whose biological parents owe the techno-mage favors.
