Horror of antarctica

Within the shadow of the arctic mounts of ice,
night had veiled the pole and darkness filled the sky.
the air was so cold - cutting our skin,
Freezing voices called us and the winter winds did sing:
"tekeli-li, tekeli-li" through the night...
What ghoulish creatures brought 'em forth?
what sphere had opened wide?
"tekeli-li, tekeli-li" sounding through the air...
Where it did lead us to, no mortal man should dare.
right before our eyes of monolithic size,
one labyrinth of cities - draped in moonlight - did arise
"tekeli-li, tekeli-li" through the night...
leading to the icy ruins
a long forbidden site...
"tekeli-li, tekeli-li" through the night...
Build by horror creatures
from beyond our spheres of light...
