Turusch

The Turusch are a slug-like alien race native to Venus-like atmospheres. They are part of the Sh'daar empire, and serve as their primary military force. They are the primary antagonists of Earth Strike, the first book of the Star Carrier series.

Anatomy
Turusch have slug-like bodies, about three meters long. The forward third of a Turusch is covered in armor plating, including its "head," which splits open into three pieces to reveal its mouthparts. It has around two dozen eyes on its front, and several tentacles distributed around its body seemingly at random. Turusch are colored a mottled red-brown.

Biochemistry
Turusch respirate carbon dioxide and sulfur, not oxygen. They use substantial amounts of sulfur, and their digestive juices consist primarily of sulfuric acid.

Diet
Turusch are carnivorous liquivores. They feed by injecting sulfuric acid into a prey animal with a rigid, meter-long proboscis and sucking up the resulting slurry with a soft feedtube joined to the proboscis. However, they also have a chlorophyll-like chemical in their skin, allowing them to photosynthesize the ultraviolet radiation of their home sun. This allows them to go without food for extremely long periods.

Psychology
Every Turusch is, quite literally, of three minds. The Mind Above is primitive and animalistic, and does little but react to threats. The Mind Here is the rational mind that carries out most of the Turusch's sapient thought processes. The Mind Below is a merger of the Mind Above and the Mind Here, and also contains a Sh'daar Seed, an artificial construct that acts as a representation of the Sh'daar's will. The Mind Below's decisions take precedence over those of the other two, although the Turusch still has great leeway in how it chooses to execute those decisions.

In addition, Turusch are "paired." Turusch form pair-bonds of such intensity that they are effectively one individual, and are addressed and treated as such by their peers. These life-pairs perform all tasks as a single unit, even speaking in unison. Turusch language consists of three statements made at once; one by each member of a life-pair, and one formed from the modulation of the other two. The death of one member of a pair is emotionally devastating to its counterpart, and greatly hinders its ability to speak and otherwise function.

Technology
While limited by Sh'daar decree, Turusch technology is highly advanced, at or above the level of 2400's humanity.

Power
Turusch spacecraft and weaponry are powered by quantum tap power plants. These consist of a pair of black holes rotating each other and extracting energy from vacuum, allowing essentially limitless energy.

Spacecraft
Turusch spacecraft are generally metallic and fixed in shape. The larger crafts are sometimes made out of asteroids or even dwarf planets hollowed out to accommodate power and weapons systems. These larger vehicles are also FTL capable, using a type of Alcubierre drive. STL travel is achieved by forming an artificial singularity in front of the ship to simulate freefall and produce high accelerations, enough to propel the ship to relativistic speeds. The singularity is turned on and off at extremely rapid speeds to keep it from tearing the ship apart, which limits acceleration; smaller ships are less vulnerable to spaghettification and thus can achieve vastly higher accelerations.

Weaponry
Turusch spacecraft are usually equipped with kinetic-kill mass drivers, accelerated using the same singularities they use to move their ships. They also use particle beams powered by their quantum taps, as well as conventional nuclear missiles.
