It is the era known as the New Western Calendar...  Two hundred years have
passed since mankind ventured into space.

In NWC 187, the unprecedented upheaval of the "Balmar War" (SRW Alpha) left the
Earth Sphere with undeniable proof of the existence of extraterrestrial
intelligent life - and a vast war raging beyond the borders of the Solar
System.

Greater yet was mankind's shock from another intelligent life form, the
implacable enemy known as STMC (space monsters).  Though mankind repulsed their
offensive by the slimmest of margins at the end of the Balmar War, it was
anticipated that they would return to menace the Earth Sphere again.

Mankind has nowhere to run...  And so, various projects have begun to ensure
their continued survival upon the Earth.

The "Aegis Project" seeks to shield the Earth Sphere from enemies without.  The
"Ultra Long-Range Colonization Project" is endeavoring to find a new homeworld.
And then there is the "Carneades Project"...

In NWC 188, the Earth clashed with alien and Jovian forces, as well as forces
from beneath its own surface.  Against the backdrop of this "War of Seals" (SRW
Alpha 2), the various projects drew towards completion.

The War of Seals reached its climax in NWC 189 with the destruction of the
"Artificial God Gun-Eden", which sought to seal mankind within the Earth.  Yet
mere weeks later, hints of new upheaval began to surface.

Mysterious military and alien forces prowl the Earth Sphere.  A massive,
enigmatic structure has been discovered in the asteroid belt.  And
communication with the ultra long-range colonist fleet has been lost...

A gong is about to sound, drawing mankind towards the final battle, and the
galactic climax.
