The words that best describe the Jove race in Eve are 'mysterious' and 'elusive'. They have been around with the rest of the Races for a long time now but still they have imposed impenetrable boundaries between themselves and the other races. To top that, the barrier of not being able to play the race in Eve online leaves us unable to quite pin down the features of the Jove.
Unlike some of the other races, the Jovians have had a tough life. Their initial surroundings were tough on their human bodies. Their turning to genetically altering their body makeup, therefore, was nothing of a surprise. Their thirst for more knowledge and their addiction to genetic engineering has resulted in their race bordering at the very brink of humanity!
If there is one thing pretty clear about the Jovians, it's the importance they give to acquisition of knowledge. They are millions of years ahead of the other races in terms of technological advancement. Their aversion to mixing with the other races is, perhaps, a way to keep their technological supremacy intact.
The Jove Empire is the habitat of the smallest race in the world of Eve. Millions of years ago, the Jovians altered their reproduction method to Fetus tube methods. This has hampered their population growth and reduced them to a very small number.
To add to their population woes, the Jovians are faced with a dreaded disease that inflicts extreme depression on the victim and takes away his will to live. The disease ends only in death!
The Jovians have lived in relative peace with other nations for a long time now. Their small size tempted the Amarr expansionists to challenge them in battle. But the impression of small fish waiting to be swallowed was dispelled immediately by the Jovian technological advancements. Even the Largest Empire of the Eve could not match the onslaught of Jovian weaponry. And since the humiliating defeat dished out to the Amarr, the Amarrian Empire has thought twice before taking up a similar expedition again.
All things considered, there is not much to write home about with regards to the Jovian relations with other races. Except, perhaps, for the fact that the Jovians try to keep the others at an arms length by easily providing them new technologies. Thus minimizing the need for the technologically inferior races to snoop around for something new.
