There are two Lunar Nodes -one is known as the
Head of the Dragon (Moon's North Node),
and the other is known as the Tail of the Dragon
(Moon's South Node).

The New Moon was Dec 24, 2011 in Capricorn the Horned
Sea Goat, and we now have Pluto conjunction with
both Sun and Moon at 7 degrees O Capricorn.This
lends the energy needed to pull the wool covering
(forcefully if need be) from the eyes, also
it will be a time where the integrity of Material
gains will be judged and weighed---with Saturn
in Libra at 28 degrees opposing Jupiter in Taurus with
no interference from other energies, a power struggle
will occur between what is Just and True and the Unjust
Material Gains over the last Century.
New types of Authority may manifest in strange ways, not before seen or felt, meaning presently we depend on our laws and justice systems to Maintain Order and Law in our Nations,
but what are we to do if our Law and order systems were
Judged by a higher authority as being Unjust? That is
where the force of Pluto comes in---Pluto was present in
Capricorn at almost the same degree as it was
in the founding of the United States of America when
the Constitution was signed. As Pluto returns, actions
motives intents visions are weighed and systems
that have become obsolete, abusive, or are
overstepping 'boundaries' will simply be done away with,
paving the way for something else yet un named
.... the energies
of Neptune, Venus, and Uranus will come into play
later in the year to to hopefully guide us into
Wise Choices as What We would like
Our New Earth to be like.
There are some very curious alignments happening
very curious indeed.

Oh about the lunar nodes.....the lunar nodes
work on an scalar electromagnetic level, pulling
and repelling the ocean tides, which then influence
atmospheric & geomagnetic changes. Possibly a scientific
explanation as to why the Tiamat the Chaos Dragon
was associated with the SEA.
