The Chakuun were originally a minor but warlike race. They were annexed, conquered by the Tholian Assembly some time around 1954 approximately. The Chakuun eventually offered their services as soldiers and eventually became an elite military force within the Assembly. In exchange for their services, the Tholians provided them with weapons and ships such as the infamous Chakuun ghostship.

The Chakuun shared the Tholian understanding of a dynamic, shifting cosmos. In 2254, when the Tholians realigned their territory to compensate for the shifting of stars, the Chakuun launched an offensive against the Federation, destroying colonies on Jubal and Theta Kalyb that they regarded as invasions. At the Battle of Theta Kalyb, the Chakuun succeeded in destroying the Nelson-class scoutships USS Brazzaville and USS Providence as well as the Miranda-class USS Achilles. In previous encounters, the Chakuun destroyed the colony of New Milan and a starship Claire Thorn was serving on.

New Venice was a Human colony on the planet Mars, in the Sol system. The colony was named for Venice, in Italy, on Earth, presumably by settlers that originated from that region. Gabrielle Carlotti moved to the New Venice colony after her family was killed in a Chakuun attack on her original home in the New Milan colony.

Tholian Expansionist Programs

The Tholian expansionist programs were a series of conflicts between the Tholian Assembly and the United Federation of Planets in the early to mid-23rd century. Many of the actual battles in the conflict were fought by the Chakuun, considered by the Federation to be a Tholian slave race but who thought of themselves as allies to the Assembly.

The conflict was a result of the differing understanding of territory by both powers. The Federation perceived the Tholians as aggressively claiming territory at a whim, however the Tholians believed they were simply enforcing their territory which they adjusted periodically to take account of stellar drift. It was not until 2254 that both sides came to understand each other and the conflict was brought to an end.

Attacks in the Programs

  • A Federation colony, New Milan was attacked and destroyed. Out of Gabrielle Carlotti's family who lived there, only she and her brothers survived the attack.
  • Christopher Pike and Dermot Cusack were at one time involved in the conflict and on one occasion had "Tholians all over [them]"
  • A truce between the two powers came to an end when the Tholians launched an attack at Kakrafoon. Amongst the combatants was the USS Crazy Horse.
  • The Chakuun launched attacks on colonies on Jubal and Theta Kalyb.


They had no central government of their own before the arrival of the Tholians. Just a large number of tribes that constantly fought each other. Now they do. They receive orders from the Tholians and the tribal leaders who now make up the planetary council, determine the quickest and most effective way to comply with the Tholian orders.


The Chakuun are an insectoid species with a vibrant green exo-skeleton. They walk around on 4 legs kind of like a centaur. They do not wear clothes but will carry a pair of saddle bags over their back like a horse. Their prefered hand weapon is a long 6' metal staff with a hooked axe blade on both ends.


They have a slightly simpler physiology as compared to most intelligent humanoids. However they have a very high tolerance to pain and can continue to fight even after receiving a death wound. Unfortunately, they are susceptible to extreme heat and cold.


The Chakuun hold little regard for humans, believing them to be an arrogant child race that judges other beings on human values. On the other hand they consider the Tholians to be just about one step below divine. Not only did they stop the many civil wars they were constantly fighting but they provided new technology, weapons and war ships. Most importantly they provide the Chakuun with an unlimited number of enemies for them to test themselves against.


The Chakuun do not have any religious beliefs. However they do tend to look up to the Tholians and treat them with a reverence and respect that many other species consider to be tinged with religious over tones.


Prior to their contact with the Tholians, they did not have a written language, nor do they have a tradition of passing on historical facts by any other method. As a result it would be safe to accept the fact that they do not have any form of mythology.


They have a warrior society where every male doubles as a soldier. There is no such thing as a non-combat individual. Everyone including women, children and the elderly are fair game on the battle field.


Since the Chakuun are a warrior culture they do not have any art forms. They do however have a number of athletic events, some of which could almost be considered sports that they all seem to enjoy. The only thing that all these physical events have in common is that they are all full contact and it is not uncommon for a number of participants to be injured.


As a warrior species they have a number of customs that revolve around their ability as a warrior. They have even developed a new one that is used to select those worthy of being members of the Tholian elite military force. It is a series of challenging physical events. Only those who prove they are good enough are selected to serve the Tholians.


Prior to the take over of their world by the Tholians, they were at a pre-industrial stage. Now they are warp capable and have access to all the technology that the Tholians are willing to give to them.


They receive a lot of raw resources from other conquered species that are parts of the Tholian Assembly (Holdfast). However, trade outside of the Holdfast is very rare.


The Chakuun Ghostship is a type of large starship used by the Chakuun, a subject race of the Tholian Assembly. According to Starfleet Intelligence these ships are of Tholian manufacture. They have proven to be more than a match against Federation starships.

Ghostships are protected by layered shielding and armed with a powerful Fusion caster modified for planetary bombardment. Ghostships also carried aboard them squadrons of fighter craft. In combat, ghostships were superior to anything Starfleet could fight them with. A Constitution class starship could not penetrate the ghostship's shields with its phasers and could barely survive a glancing blow from the Chakuun's fusion caster.

Against a fleet of ghostships, Christopher Pike noted a taskforce consisting of the USS Enterprise (NCC-1701) and four smaller ships was "no match".

This data is over 100 years out of date. No Chakuun vessel has been encountered since then.

Federation Intelligence Files

The Chakuun seem to be totally 100% loyal to the Tholians. Extreme acts of bravery and unusual levels of combat frenzy make them dangerous both on the ground and inside their warships. Use caution when dealing with them.
