Ka'Dath was a projection created by the sentient Hive Mind Bacteria when 2262 when Lyta Alexander and G'Kar arrived on the "Hive Mind" planet. While exploring the world, G'Kar encountered Ka’Dath, who took him to a purported colony of Narn who were the only survivors of a Centauri slave ship that crashed on the planet three years earlier. G'Kar quickly discovered that the colony was not what it appeared.
