This is the Inner Sphere.
Thousands of planets colonized by humankind.
Once it was united under the Star League, but for the last three hundred years it has been consumed by savage wars.
Until, a new enemy appered.
Mysterious invaders known as, "the Clans."
Powerful and ruthless, they struck like lightning, attacking every sector at once.
But they made one big mistake.
They attacked MY home planet.
Now, in the spirit of the Star League, ancient enemies have re-united.
And, we're gonna take back our galaxy.
