Jareb was a Triannon and a member of a religious zealot group led by Pri'Nam D'Jamat.
In November 2153, Jareb participated in D'Jamat's takeover of Enterprise NX-01 for use against their opponents in a religious war. He took over the science station when T'Pol refused to target an opposing Triannon vessel.
After Doctor Phlox neutralized the organic explosives implanted in D'Jamat's followers, Jareb was incapacitated in the firefight as MACOs stormed the bridge. (ENT: "Chosen Realm")
