Jamin was the leader of the Novans on Terra Nova in 2151.
That year, when Enterprise NX-01 arrived at Terra Nova to investigate the colony's fate, Captain Jonathan Archer attempted to persuade Jamin that he and his people were descendants of the original colonists, who were from Earth. Jamin, however, was reluctant to believe that the Novans were descendants of Humans.
Because the Enterprise crew then discovered that the Novans who were living underground were in danger because their water supply was contaminated, Archer offered to move the Novans to caves in the southern hemisphere of the planet. At first, Jamin refused to trust Archer, believing their planet was poisoned in an attack from Earth years ago, and that now Archer wanted to take their home from them. Even though Jamin's mother, Nadet, started to believe Archer – shown a photograph of a group of colonists, she recognized a quite Human child in it as her younger self – Jamin still didn't trust him.
After a Novan man called Akary became trapped under a trunk in an underground well and broke one of his legs, Jamin allowed Archer to help rescue Akary, the captain using his own phase-pistol to cut the wood so that they could lift it high enough for the injured man to break free. The incident helped build Jamin's trust in Archer. Along with this newfound trust and the word of Nadet, Jamin and the other Novans were finally persuaded to accept Starfleet's assistance.
