Over two hundred and fifty years ago, General Aleksandr Kerensky departed human-occupied space, taking three-quarters of the Star League Defense Force with him. They returned in 3050 as the Clans: a society dedicated to the highest warrior ideals and bent on conquering the Inner Sphere. With their OmniMechs and superior technology, they proved almost unstoppable until their defeat at Tukayyid and subsequent 15 year truce. The year is now 3071, and the Jihad rages. Inner Sphere ˆ_Ñé_Mechs, hastily upgraded with field modifications to counter the Clans, continue to prove their worth. Notable pilots rise to become heroes as new, time tested variants--sporting weapons right out of R&D labs--make their presence known.
