It is an Irony that the Metaphasic Radiation that kept the Ba'ku in an almost ageless state, living for hundreds of years, and brought about the impatience of those who would become the Son'a was essential in extending their life spans considerably, even after the Son'a left the planet. However as a species who have lived for hundreds of years without aging a day, the change that overcame them as they began to age was considerable, they ceased their exploration and became wanderers searching for immortality, believing themselves unwelcome with the Ba'ku. As the years stretched on their search became more desperate and they turned to drugs and medical techniques to extend their rapidly diminishing life spans, turning to piracy and violence in order to fund their macabre pastime, eventually conquering other species to serve them, the Ellora and the Tarlac.

Rua'fu, their leader came up with a plan to regain the years they had lost. It would take time, but with the best medical treatment, they could expand their life spans to ensure its success. They could simply harvest the Mataphasic Radiation, using it to enhance their bodies. Of course such an action would lave the Ba'ku home world uninhabitable, but this pointless act of vengeance against the Ba'ku only spiced the plan. Then it was discovered that their bodies had been treated to the limits of their endurance, and that it would be unlikely that further treatment would have any lasting effect, and with preparation nearly, but not quite, complete, the Son'a were forced to make an Alliance to complete their preparations, they chose the Federation, relying on the naivety of the Federation to ensure the plans completion and cover their devious acts.

But the intervention of the USS Enterprise under Captain Picard thwarted their plans and for a small number of Son'a drew the 2 very different species back together again. However many Son'a still feel this is propaganda, or appreciate thei lives as they are and continue on.

The S'ona are very wealth oriented, they collect treasures and fine objects d'art. Over the years they have become wealthy and influential as Pirates and Traders, working independently or with others.

They are also particularly fond of ostentatious displays of wealth, proudly displaying precious metals and stones as part of their outfits. They have also become influential in crime, and it is rumoured that at least one Son'a serves among the leadership of the Orion Syndicate. Independent Son'a have become even more dangerous since the cessation of hostilities with the Dominion, recent intelligence believes that many Jem'Hadar Alpha's abandoned when the Dominion signed the peace treaty were given haven by the Son'a, the fact that the Son'a had developed a production technique for Ketracel White only enhances the likelihood of these reports but confirmation is being sought.
