According to Captain Jonathan Archer, more Tarkaleans served aboard the Tarkalean freighter in 2153 when it was assimilated by the Borg.
When Enterprise NX-01 beamed her aboard she was unconscious. She was brought to sickbay where Doctor Phlox cared for her. When she woke up, she attacked Crewman Foster who guarded sickbay and threw him across the room. Then she left together with the male by using a ladder into a maintenance shaft.
She stopped in maintenance shaft C junction twelve where she started to modify the ship's systems by using her assimilation tubules. When a security team led by Lieutenant Malcolm Reed engaged her and requested her to stop she ignored them. When the team fired their phase-pistols and phase rifles at her and again after they increased the setting, her personal shielding was activated and she walked towards the group which withdraw.
This Tarkalean was also working aboard the Tarkalean freighter in 2153 when the Borg assimilated him. Assimilated by the Borg nanoprobes and unconscious he was examined by Dr. Phlox in the sickbay aboard Enterprise. When he woke up he asked where he was and who Phlox is and became furious. Phlox was up to inject him a sedative with a hypospray but he grabbed the Denobulan, injected him the assimilation tubules into the neck and threw him over the biobed. Together with his female companion he left sickbay using a ladder to the maintenance shaft.
Later, he attacked a security team led by Lieutenant Reed and disarmed two security officers before Reed knocked him down with the shaft of a phase rifle.
Around 2372 the Federation started trading with the Karemma using the Ferengi as intermediaries. However, the Karemma complained about an abundance of taxes and fees. Among these fees, of which Starfleet was unaware, was a six percent tariff on Karemman fleece, to help offset the lost income of Tarkalean sheep herders. Quark described them as a "hardworking people". (DS9: "Starship Down")
