planet X is the atlantian homeworld. though the high council never visit the planet, they believe that it is the birth place of the atlantian civilization. the fact that when they send more of the atlantian city platforms to aid the dragons in their campaign against the atlantian kryll serves to conferm this. the platforms constructed on this planet posess weapons more advanced and powerful then those of the platform discovered in the burned lands by cynder. Dragon kind's contact with the atlantians will eventully lead to conflict with the [illuminati]and to the discovery of the lost aztec temple-fortress of t'hochec.
