Here at the far edges
of existence
:06:19
the wildness
of the ancient earth
:06:21
never vanished.

the solitude of the past

is broken only occasionally
by the sound of the present.

the last great lce Age survives.

Vast regions appear as lifeless
as a frozen planet.
:07:15
Sheer walls a mile deep
loom as monuments to the power
:07:19
of the glaciers
which carved them.

Most of its rugged terrain
can be crossed only with wings.
