We learned the hard way what had spun these crystalline webs in the tunnel. A spider as big as a horse, with shiny skin made entirely of crystal that vanishes before our eyes and reappears elsewhere. Each of its eight legs ends in razor-sharp claws, and its ice-blue eyes glow menacingly in the darkness.
It seems to be defending its nest at the end of the tunnel. We can see large crystalline eggs of various sizes inside, pulsating with gentle light. The spider guards them jealously and attacks us as soon as we approach. We must be careful not to fall into its clutches.
