It had been a maze before, back when it was easy to tell the difference between rock and built stone at a distance. Now it was even worse. There were constant low light conditions, made worse by the darkened environs. The false starlight provided by the ephemeral beauty of the luminescent moss and plant life that covered the cavern ceilings was not enough anymore. What little light provided by the strange chitinous substance itself at times didn't help matters. The dominant colours of light was green, but some buildings emitted orange or blue and other soft colours from parts of the strange substance that covered everything. That only helped to cast everything that was partially illuminated by them into soft shadows. The only 'normal' lights could be seen from within buildings through windows that had been left open by whatever changelings were foolish enough to risk it.
