Jono

Jono, born Jeremiah Rossa, is the Human adoptive son of the Talarian officer Endar and grandson of Starfleet Admiral Connaught Rossa.

The son of Connor and Moira Rossa, Jeremiah was born in 2353 at Galen IV colony. Jeremiah's parents were both killed during a Talarian attack on the colony during the Galen border conflicts in 2357. However, he was subsequently adopted by the Talarian officer Endar, who treated him like his own son and gave him the name Jono. He was rescued by the Enterprise-D in 2367 from a disabled Talarian starship. When Captain Jean-Luc Picard discovered his identity, he tried to bring out Jono's Human side. Jono at first responded, but later tried to kill Picard by stabbing him. He did this hoping he would be put to death and would not have to choose between his Human side and Talarian side. He finally decided to stay with his "real" father, Endar. (TNG: "Suddenly Human")

Pendragon Timeline
Jono rose through the ranks in the Talarian military and eventually became a respected commander. He opposed raids into Cardassia and the Demilitarized Zone in the 2370s.

After witnessing the horrors his adopted people had inflicted on the Cardassian and DMZ survivors, he sought to be a peacemaker.

While infiltrating Xe'na'zha in the Badlands in late 2385, Jono's life was saved by Benjamin Dunkerton. (PDN: "Above the Wrecks of Time")

In 2386, Jono became Talarian Ambassador to the Colonial Alliance, though he maintained his Captain rank in the Talarian space fleet.
