True children would have perished very quickly in such a place- the pungent chemicals that misted the air would have disolved the tissue of their lungs- but these were not true children. They had been so long ago, before extensive surgeries had converted them in ageless amalagams of flesh and metal like the tech-priests they served, only far less sophisticated. Their brains had been cruelly cut, rendering them incapable of independant thought and their voices had been silenced forever. Their only function was to obey and, as such, they were beyond sin, mischief or evil. Perhaps in recognization of this, their creator had crafted bronze masks for them, faces frozen in beatific smiles, like half living sculptures of holy cherebium.
