History and specifics
In the year 2370, the USS Enterprise-D searched the Mekorda sector for potential Federation colony sites. The search was unsuccessful due to the lack of habitable planets. A magnascopic storm occurred during the survey, enveloped the Enterprise, and indirectly led to the birth of a new lifeform on stardate 47869.2.
Following the storm, emergent circuit nodes took control of the Enterprise and directed to potential sources of vertions. The nodes first visited the white dwarf star Tambor Beta-6, then proceeded to the Cordannas system. The Enterprise crew managed to redirect their ship to the MacPherson Nebula. Finding a source of vertions, nodes developed into the emergent lifeform, which left the ship. (TNG episode: "Emergence")
