Suddenly the light disappeared.

I stood still for a moment in surprise, and when I again went forward I became speedily conscious that all our companions had vanished, and that we stood alone in utter darkness.

Fearing to lead Eveena further where my own steps were absolutely uncertain, I paused for some time, and with little difficulty decided to remain where I was, until something should afford an indication of the purpose of those who had brought us so far, and who must know, if they had not actual means of observing, that in darkness and solitude I should not venture to proceed.
Presently, as gradually as in Northern climates the night passes into morning twilight, the darkness became less absolute.

Whence the light came it was impossible to perceive.

Diffused all around and slowly broadening, it just enabled me to discern a few paces before us the verge of a gulf.
