The Korhonen are advanced physically, however their technology fails to reflect this. The Korhonen brain an sensory organs are highly developed. This accounts for their advanced telepathy. On the other hand the digestive system appears to have developed little. The Korhonen have a single 4 chamber heart, when compared to the Human heart it appears more compact and advanced. This allows faster mobility. The blood is a green substance similar to chlorophill, found in plants.
The Korhonen appear to be absent of reproductive organs of any kind, the way in which the Korhonen reproduce remains a mystery to scientists. Also genitalia are absent, waste products are believed to be disposed of through the skin, in the form of sweat.
The Korhonen are approximately two metres tall. Their eyes are large almond shaped, the nose is about half the size of a human nose and a slit represents the mouth. The Korhonen themselves rely on technology heavily, this could be due to the fact that they are weak physically. In space combat however the Korhonen are usually the Victors, due to their ability to think fast and understand complex strategy and due to the fact that they can handle high G-forces

The Korhonen have demonstrated the ability to induce fear in the minds of their enemy. This is due to the high levels of telepathy they posses. Telekinesis has been witnessed, the abilty to handle small objects with your mind, on numerous occasions. 1 in 10 Korhonens posses telepathy and 1 in 100000 Korhonens display Telekinetic ability. abilitys.

The Korhonen social structure is made up of 5 groups. The J'taq handles military affairs, J'pah handles political affairs, J'gaq handles social affairs, J'kah handles economic affairs. Another group, the J'kaq, has been observed however it is shrouded in secrecy.
It is believed that the J'kaq have several underground installations on the Korhonen homeworld, Ganymede and several other planets/moons.

The Korhonen homeworld, Zeta Reticuli III, from a distance looks similar to earth. However upon close examination signs of massive underground complexes can be seen. Major cities are rumored to be beneath the surface. This would explain why 60% of the surface is devoid of Man-made structures. The only pictures of the Korhonen homeworld were produced by the Hubbel array in Earth Orbit. Any ship which survives long enough to scan the Zeta Reticuli system without being destroyed by Korhonen cruisers will reveal a fleet of over 1000 ships, its purpose unknown.

The Korhonen posses a complex language, it took 76 super computers (A5000/666 models) on 4 continents to decipher the Korhonen language. A chart has been produced which has basic translation information.
The numerical system is reminicant of strings of equations.

Little is known about the Korhonen after 2040. Since their defeat by the combined Earth and Morgenson forces they have entered a period of isolation and secrecy.

The korhonen are easily offended, particulary their death ritual. Bodies of their dead are sacred, it is a great offense to perform an autopsy of any kind.
Since 2040 several outer outposts have been abandoned, no reason has been given. The central systems of the Korhonen Enclosure have been heavilly fortified. Around their homeworld, Zeta Reticulii III, a fleet of over 1000 ships has been formed. Also, a lot of Hyperspace activity has been noted in the same area, one explantion could be that ships are constantly entering/leaving hyperspace to hide their numbers, or their could be another reason.
Only the outer worlds are open to visitors, anyone who strays into the central systems is never heard of again. A flight recorder from the SS Collingwood has been found, it confirms reports of a massive fleet.
