Kahler

The Kahler are a species from the Doctor Who Universe. They are most famous for their technological skills.

Physical Characteristics
Kahler look identical to Humans except for green patterns on their faces. These patterns are unique and can be used to identify an individual.

Homeworld
The Kahler come from a planet that is also called Kahler. During a war that lasted nine years, half the planet was ravaged. Other than that, little information is given. The Gunslinger says that he is from an area called Gabrean. Kahler-Jex states that he knows that area and says that it is a beautiful place.

Culture
Individuals were always identified with the word "Kahler" in front of their name. They worship gods and believed that after dying, you had to climb a mountain carrying all the souls of those you've wronged.

Technology
The Kahler were most famous for their technology; the Doctor called them "one of the most ingenious species in the galaxy". They had spacecraft, hovering robots, teleportation, and could easily cure cholera.

During a war in the 19th century, they created an army of cyborgs using Kahler soldiers. These soldiers were equipped with a powerful energy weapon, an eye lens that had an automatic targeting system, sensors that could see through walls and identification software. They were also fitted with a short range teleport device.
