The Babylon Project

The Narn Expeditions to Z'ha'dum were missions sent to where the Narn government, the Kha'Ri, believed a dark and ancient race lived.

G'Kar mentioned such an expedition during a council meeting, after which Londo Mollari relayed the Narn's actions to Morden. Morden made sure that a vessel was waiting to destroy the Narn ship as it exited Hyperspace.

The destruction of Narn expedition vessel was ruled an accident, and the Narn put a stop to all further expeditions in the region of space.[1]
