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...
