"Prologue" by Bal-sagoth

In 2104, lithological excavations at the Fourth Mars Colony
unearthed
an artifact of unknown, seemingly non-human origin; an
icosahedron of
an unrecognized, non terrestrial metallic composition,
inscribed with
strange, indecipherable sigils and glyphs.

After long months of intense study, epigraphy experts on
Earth ascertained
a tenuous parallel between the unknown language on the
icosaherdon and
certain obscure Aztec hieroglyphics, and thus were able to
extrapolate
a meaning from the unearthly inscriptions.

The translation spoke of a legendary repository of ultimate
knowledge
known as the Empyreal Lexicon... a codex of alien origin
said to contain
incredible cosmic secrets; arcane words and psionic waves of
power which
were the keys to unlocking a network of
cerebral-transferrence portals
linking the myriad galaxies of the multiverse, and also the
means to
transcend the boundaries of the space-time continuum,
enabling corporeal
beings to travel between dimensions and traverse at will the
unknown
realms which lay between universes, tapping into the
limitless energies
which permeated the sidereal fabric of the cosmos.

The translation of the Mars icosaherdon also hinted
disturbingly at a
great pangalactic conflict which was waged over the
possession of the
codex between the mysterious cosmic beings who had appointed
themselves
the keepers of the Lexicon and some terrifying shadowy foe
mentioned
only fleetingly in the alien text.

The final battle in this cataclysmic power struggle was
apparently fought
in Earth's own solar system, and the Keepers of the Lexicon,
their power
depleted and teetering on the verge of defeat, shattered the
codex into
a myriad shards, scattering the fragments across the star
system in order
to prevent the secrets of the Lexicon from falling into the
hands of their
darksome nemesis.

According to the Martian artifact, several fragments of the
Lexicon
were hidden on the third planet from the sun, the Earth
itself.

One fragment was secreted in ancient Atlantis, another in
Lemuria.
Further pieces of the cosmic codex fell to earth in Ys and
eon-veiled Mu.

Still further fragments of the Lexicon were said to have
been hidden
somewhere beneath the frozen surface of the bleak moon
Callisto, and
on the other mysterious orbs Hyperion and Titan.

Lastly, the alien artifact spoke mysteriously of something
hidden
beneath the cratered surface of Earth's own Moon.

Ascertaining co-ordinates from the Mars icosahedron, an
expedition
embarked immediately from the Epsilon IV Moon Base and began
to excavate the lunar sphere.

Thus was a veiled warning unheeded, and no one could know
what
to expect as the machinations of humankind breached the
ancient
surface of the moon's Mare Imbrium...
