OK, so after reading a bit of this topic, I just can't resist the urge to think-up some "timeline facts" that would be cool..
These are totally made up, but would be cool if it happened..
3151 - In an attempt to return to former glory, Clan Jade Falcon scientists in the Eugenics program create a new super-human genome. called "Alpha Strain". This modification contains bits and pieces of the various blood-named warrior DNA, and the result is a stronger, faster, smarter humanoid, build and designed to make use of a new technology - Technomancy. This technology is based on a cybernetic implant that merges man and machine seamlessly, making a mech pilot's reactions and movement as fast as his natural movements, while also adding a significant boost to an Alpha strain subject's natural psychic abilities. This all results in a super-fast, super-strong and telepathic warrior capable of assaulting enemies both physically and mentally.
3154 - All new Jade Falcon warriors produced are using Alpha Strain. Mass production takes place, and soon, Alpha-men number in the millions. Alpha-men see themselves as superior in every way, and seek to take command away from Falcon leadership. In a daring raid, Alpha men assassinate the Khan, and their leader Zyon Prime becomes Khan. Non-alpha clansmen are reduces to second grade citizens. Many defect to other clans, and an underground splinter movement called "The Jaded" is formed on Strana Mechty.
3155 - Khan Zyon Prime announces the full scale production of a new Assault omnimech - the "Hammer". This mech is faster and better armed than any other assault mech in existence, and made to use technomancy. It's main strengths lies in it's maneuverability, while carrying a heavy weapon payload. "Hammers" are mass-produced, and soon, all the other great houses and clans fear it's name.
3156 - Members of "The Jaded" menage to steal plans of the Hammer mech, and smuggle it to Clan Wolf in Exile, from where, it gets distributed to most of the great Inner Sphere houses for analysis, only 4 months before..
3157 - ..Clan Jade Falcon's Khan Zyon launches a wide-spread invasion of the Inner Sphere, breaking any and all war conventions and treaties. He announces that "humans" are inferior, and should be purged from the sphere, or subjugated, clansmen and freebirth alike. This xenophobic stance leads to open warfare. Lyran Commonwealth is first to be attacked, followerd by Clan Wolf, and Clan Hell's Horses. The Falcons make quick progress, spreading like wildfire, and soon, Clan Wolf Khan is forced to petition for aid from the Great Houses of The Inner Sphere.
3158 - After loosing much ground to the Falcons, Khans from Clan Wolf and Clan Hell's Horses, and High nobles of the Lyran Commonwealth, Draconis Combine, Republic of the Sphere and the Federated Suns, along with representatives from all the other great houses and factions agree to meet on Terra to discuss the Jade Falcon invasion. An initiative called "The Terran Alliance" is formed, but just as the treaty of mutual joint-efforts and cooperation in the war against the Falcons is to be signed, an alpha-man disguised as a member of "The Jaded" dominates the minds of all present, and forces them to kill each other bare-handed. A great brawl ensues, and the last man standing, a Draconis Combine noble, snaps his own neck . This throws all the factions into chaos, as new leadership is needed to address the overbearing xenophobic Alpha-men of Clan Jade Falcon.
3159 - Clan Jade Falcon has spread like wildfire across the Inner Sphere. Many of the smaller factions have capitulated, deciding it's better to be slaves to the Alpha men than to die. Parts of the surviving houses and clans have formed "The Terran Alliance". After initial infighting, the right to lead has been decided by a Trial of Bloodright between the finest of all the candidates. The sole surviving candidate has become "Primus" - A man named Tyron Khall - a freeborn Clan Wolf Bondsman from the disputed regions. Tyron is given a heavy task - Lead the united factions of the Terran Alliance and defend the Inner Sphere against the threat of Clan Jade Falcon..
Aaaaaaaand... Que Mechwarrior "NEXT"
