The Aldeans were a civilization native to the Alpha Quadrant. Their home world of Aldea was considered only a legend for thousands of years.

The society was self-contained and self-sustaining with incredible technical sophistication providing daily needs. Similar to cultural myths of Neinman on Xerxes VII or the Earth story of Atlantis, Aldea was said to have shed its past of violence and cultural conflict and evolved to a pure state, devoting themselves to culture and art. The Aldean culture developed by emphasizing the fundamental principle that for "everything taken, something must be returned." It was this principle that allowed their civilization to ascend to incredible heights in technology and art.

Having reached enlightenment, the Aldean society retreated from the rest of the galaxy. To facilitate this, their progenitors built an enormous and advanced planet-wide defence system. The system, run by the computer called the Custodian, maintained an immense cloaking device and defence shield, in addition to a repulsor beam powerful enough to push star ships several hundred light years away.

However, the long-term effects of the planet's defences were extremely damaging. Millennia after the Aldeans retreated behind their cloak, cumulative wide-spread environmental damage, including depletion of their ozone layer, began to take their toll. The Aldeans suffered from long-term chromosomal damage from radiation poisoning due to exposure to their sun's ultraviolet rays. By 2364, the entire population of Aldea was sterile and depleted. No child had been born on Aldea for more than thirty years, and most of native wildlife on the planet, including all the fish in their oceans, had long ago become extinct.

Desperate to preserve their society, the Aldeans, led by Radue contacted the USS Enterprise-D for help in repopulating their planet. Unable to reproduce themselves, the Aldeans offered to exchange their vast knowledge for a select few of the Enterprise's children. The Aldeans were physiologically very similar to Humans, which presumably was a deciding factor when they contacted the Enterprise. The Enterprise turned down the offer, leading the Aldeans to kidnap the children, creating a stand-off that was eventually resolved when the Enterprise proved that the very thing which had protected Aldea, its cloak, was responsible for their condition.

The Aldeans returned the children and set about re-learning their own technology and adjusting to a new galaxy where they were no longer just a legend.


They have a council of elders chosen for their intelligence, knowledge and abilities.


They appear to be humans.


Other than the sterility that has been a caused by long term exposure to their own defensive and protective systems they tend to be very healthy. While their internal organs are set up slightly different from humans they still have a fairly basic anatomy.


They tend to be fairly stable as a species although they do admit to a few age related mental ailments. There is some belief that this is also a side affect of prolonged exposure to their protective and defensive systems.

Aldean society was structured into units, or social groups, which specialized in a particular art or pursuit such as medicine or science. Within each group students were fully devoted to their discipline. The Aldeans had perfected their system of education and study to the point where the natural abilities of the individual blossomed very quickly, sometimes within hours or days of the student's first exposure to a medium.


They have a rich culture with a love for music, art and other creative forms of expression. In fact they have imported as many different examples of these art forms as possible.


Unknown at this time.


They easily surpass Federation standard levels of technology in many fields. So far they have revealed very little of this knowledge to any outsider.


They are completely independent but they do import medical and artistic knowledge. So far they have only exported medical knowledge and various forms of artistic expression.


They have no military at all. Their protective and defensive systems protected them for thousands of years. They do however maintain a very small but highly trained police force.
