Prologue

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....
