Lyrics:

They were rising.
Not at a great speed,
but their upward motion was irrefutable.

The hot bubbling water that surrounded them
gradually began to inspissate
ultimately becoming a thick, boiling lava paste.

A heat haze, created from the hot vapours,
hung menacingly above the angrym molten surface.
Unlike the dormant crater of Sneffels,
where they had begun their journey,
the volcanic shaft they were now in was active.
The intense heat, eased only by the now incredible rapidity of ascent,
was almost unbearable.
A sepulchral light penetrated the vertical gallery
as tongues of fire danced all about them.
The absence of burning lava
confirmed that they were not in the main shaft of the volcano,
but in a parallel, accessory conduit.
Their continual rate of ascent grew at an alarming pace
as they fought their way through burning clouds of volcanic cinders
toward the opening of light above ,
itself racing downward, at equal velocity, to meet them.

Upon reaching the yawning mouth of the auxiliary shaft,
their speed decreased rapidly,
and they found themselves gently floating away
from one of the myriad of earth's pores
that littered the mountainside.
Numerous additional streams of lava ran all around them
like fiery serpents seeking out their prey.
In realative safety they watched the main eruption
fire vast amounts of molten lava high into the air.
Three thousand miles from their original starting point,
amidst the eastern archipelago of mythological memory,
they gazed in wonder, as had the journeyers
of two hundred years before them,
upon the Blue Mountains of Calabria
and the mountain that had expelled them, Mount Etna.

So ended 'The Return To The Centre Of The Earth'.
