Ha'rok was a Narn Counsellor. In 2258 he was sent to Babylon 5 by the Kha'Ri to approach the Dilgar war criminal Jha'dur on behalf of the Narn Regime to secure the secret of her universal anti-agapic serum. However when attaché Na'Toth, who was waiting for him in Passenger Lounge recognised and attacked Jha'dur because of her family's Shon-kar, Ha'rok was forced to return to Narn, leaving the matter in Ambassador G'Kar's hands.
