A representative of the Caatati, a people left homeless by the Borg, who appeals to Captain Janeway for food and medicine for his starving shipmates.
Rahmin is one of the few thousand Caatati to survive the assimilation of their world. He appears in the fourth-season Voyager episode Day of Honor.
He comes aboard Voyager to ask for help, describing ships crammed with hungry refugees. Janeway gives what she can spare. The Caatati are grateful, but the presence of Seven of Nine, a former drone living freely among the crew, stirs up their bitterness towards the Borg.
His plea is followed by more demands from other Caatati under Lumas, who eventually surround the crippled Voyager. The stand-off ends when Seven builds them a device to produce thorium isotopes.
