History 
The planet itself was virtually uninhabitable, with a surface characterized by lava flows and lakes of acid; the Majalans lived on floating cities that hovered high above the inhospitable planet. 

In ancient times, the s of Majalan society developed technology that would allow them to build a civilization on levitating platforms high above the hostile surface of their homeworld. However, this machinery required the neural network of a child to function, and once connected that child would be irreversibly condemned to a slow, painful death. The reasons for this design, and the exact workings of the machine, were eventually forgotten.

Despite centuries of searching, the Majalans were unable to find an alternative to using a child to sustain their society. Believing nevertheless that the suffering of one was worth the benefits to the rest of their people, they decided it best to face this bargain openly. The sacrifice of the child was elevated to religious significance: a sacred "ascension" to be carried out willingly by the "First Servant", a holy figure to whom all Majalans were devoted and grateful.
