GNOLAMS

Planet of Origin: Gnol

The Gnolam are peaceful diminutive bipedal species from a low-gravity planet that was often described as dwarf- or gnome-like. They possessed an amazing ability to create and horde treasure, and their dictators almost never lacked money. Gnolams also had strong knowledge of business, resulting in large profits from trade routs and extra food sales. In addition to all this, Gnolams had amazing luck. Perhaps this power was their attempt to counter the Elerians mental powers; Space monsters and Antaran fleets almost always ignored Gnolam planets. Disasters never befell the Gnolams, and unexpected fortune came frequently for them Their biggest enemy are the Elerians.

TRILARIANS

Planet of Origin: Trilar
The Trilarians are a species from an oceanic world and lived in water. They developed an honorable and peaceful interstellar civilisation. Their ships were among the faster due to Trans-Dimensional abilities supposedly came from the Antarans; the Trilarians claimed that they were the descendants of a lost Antaran colony. Our evidence seems to indicate that the Antarans indeed had a presence on Trilar and even interfered in Trilarian species development.

ELERIANS

Planet of Origin: A planet orbiting a star in Draconis
The Elerians are a species of fairy like bleu skinned humanoids that developed a space faring civilisation. They are a feudal matriarchy, in which only females (the warrior caste) could join the military. Elerian mental powers are beyond compare; their males in the philosopher caste can detect everything taking place in the galaxy, from the biggest fleet to the most distant tiny planet. The females also have some strong telepathic powers. Their large ships always have onboard a powerful telepath who can mind-control an entire planet, eliminating the need for ground troops. The ship leaders can also see slightly into the future, giving noticeable attack and defense advantages. They could even take mental control of a captured ship and use it in the same battle against its former fleet. Their only seeming weakness is their weak government, in which the local rulers have considerable influence over their planets. Science is not one of their high priorities.

SAKKRA

Planet of Origin: A world orbiting Sssla
The Sakkra are a reptilian species which developed an aggressive and expansionnist space faring civilisation. Knowing a quick demographical growth, they are always looking for new planets to colonize. They are very advanced in planetology and good at terraforming. Their enemies include the Alkari, Darloks, Klackons, and Meklars, and especially the Mrrshan. They did like the Humans, however.

SILICOIDS / CRYSLONS / GEODICS

Planet of Origin: A planet orbiting the star Cryslon
The Silicoids are hostile expansionnist crystalline beings. Their population grow slowly, but pollution and hostile environments do not harm them at all. This allows for early colonization of rich, hostile worlds. The Silicoids are skilled at new computer research, but poor in all other fields of technology. Their fleet preferred larger ships. Silicoid emperors were usually hostile and expansionistic.

MRRSHAN

Planet of origin: A planet in the Fierias star system.
Mrrshan are an aggressive feline humanoid species which developed an expansionnist interstellar space faring civilisation.
