Ullians
The Ullians come from the Ullian homeworld an independent and neutral planet within the borders of the Federation. While they are not Federation members, they are advanced enough for full contact to exist between the two cultures, and a friendly state exists between the Ullians and the Federation.
Ullians are telepathic species and possess the ability to telepathically retrieve the hidden memories of other humanoids after years of specialized and intensive training. Using this skill, the people have embarked in amassing a library of history that is researched by retrieving personal memories of many worlds' individuals. Fellow telepaths can monitor each other, and often do out of fear of what has been termed "telepathic memory intrusion," considered to be akin to rape in their culture.
It is a legacy of one of the darkest times of the Ullian history that such an abominable occurrence is linked to their ability to share memories, dating back hundreds of years when a small few Ullians took their own pleasure from committing such a heinous act.
So dreadful is it considered that the harshest penalties are used on those that commit it, effectively lobotomising the criminal. A punishment that seemed to be successful in curbing and controlling this crime. For at least three hundred years this crime had died out, until Stardate 45429.3 when a similar offence was carried out against members of a Starfleet crew during transit.
The Ullans are a humanoid race, distinguished in appearance by lightly upswept eyebrows and a rough-textured membrane that covers the top of the ear and melds flush to the head along a line with their larger ears.
The Ullians are a race of Telepaths who have cultivated their natural ability for memory retrieval to help share memories, and even rebuild lost and forgotten memories. This is predominantly a learned capacity, using a combination of Psionic Stimulation and careful questioning of the subject in order to recreate the full perfect memory rather than rebuild and extrapolate from only a glimmer of memory.
To the Ullian culture, true history is that of memory rather than written accounts and records. They see memories as personal accounts of lives touching the times they pass through. And the Ullians are attempting to recreate a historical archive of such Psionic data, gathered from their own people and anyone willing to share their lives with such an archive. Whether it be a simple memory or a recollection of a series of important encounters… And since their encounters with the interstellar community, they have expanded this archive to include memories and experiences of those on neighbouring planets or that travel the stars, with plans to expand the Archive further as required.
Those that show interest in pursuing the path of building this archive, undergo years of training and study, in order to properly learn how to draw a true an accurate memory and to store such a memory for later addition to the archive.
After a pre-history that seems to echo the Vulcan ancient history of violence and telepathic terror, the Ullians have only claimed a peaceful heritage within the last few hundred years, and like humanity are still trying to live down such recent violence and disaster in their history. Perhaps it is these two aspects of Ullian history that explains their kinship with both Vulcan and Human members of the Federation.
One of the key elements of their new steps of peace, seems to have been the creation of their memory archive, and solid evidence of the loss of the historical lessons allowing a direct application of the memories of those that suffered war and violence to discourage similar actions.
However one oddity of the Ullian species, especially when considering their telepathic abilities, is that the complex structure of the Ullian mind, in conjunction with their sense of discipline makes them highly resistant to the scans of other psychics, with such attempts proving difficult and taxing to the Psychic.
