"Ever since the time of the great cataclysm, the Arkadians have lived deep in the center of the Earth. They believed they were the only survivors of this great devastation. Their civilization thrived under the power of their sun, the Terra...until it began to fail. In desperation, the children of Arkadia broke the law and entered the forbidden archives searching for a solution. What they discovered gave them hope. Anxiously, they used their special powers and created a messenger to the people above. They named her Arkanna..."

Arkanna was joined by Spartakus (a rebel slave and wanderer that possesed a magical armband), Matt and Rebecca (two children from the surface world), and Bic and Bac (two anteaters and the oldest creatures from Arcadia). Together they journeyed through the Strata, a world that lies below the Earth's surface, aboard Tehrig, their living ship, uncovering the long forgotten secrets of Arkadia's past. The series was known as "Les Mondes Engloutis", or "The Absorbed Worlds", in France. [Special credit to: badkitty0404]
