R'Kayza was a former Gand findsman, who left his homeworld to pursue a career first as a bounty hunter, and later as an assassin. He built a sturdy reputation as a cold and swift killer, choosing to employ subtle, stealthy tactics, unlike Haelon Tice, his longtime partner, who preferred a more direct approach. Together, the two assassins worked for an Anomid informant named Yin Vocta for over twelve years, accumulating an impressive tally of successful kills.
