Disclaimer – Don't ask cause I don't own it. CBT or seed

A/N now I know the question will be posed to me "WTF made this come to mind". Well frankly it was an idea I had spawned during a "discussion" with a friend about Gundam beam weapons Vs Lasers from Mechwarrior. Now I know some of you are not familiar with Battletech so at the start of this brief back history for this story I'll post a terminology list and some explanations. Those of you who are familiar with it can skip this. Also if I miss anything you want explained post it in your review and I'll put it at the start of the next chapter. Also not some of these terminologies are based on what is given in the Battletech Wiki, to which I shall give credit as it and the Technical Readout books are my main sources of info. And yes this will take place on another planet deep within the Federated Suns. Changes have also been made to the Gundams, which you probably expected, the descriptions of which will be added in this at the end of the timeline. At the time of this posting the actual 1st chapter is at 19 to 20 percent completion.

Battlemech Gundam Seed

Preface

Terminology

House Davion – ruling family of the Federated Suns, capital on planet New Avalon

House Steiner – ruling family of the Lyran Commonwealth, Capital on planet Tharkad

House Liao – ruling family of the Capellan Confederation, Capital on planet Sian

House Kurita – ruling family of the Draconis Combine, Capital on planet Luthien

House Merik – ruling family of the Freeworlds League, Capital on planet Atreus

Inner Sphere – region of interstellar space surrounding Earth to a radius of roughly 450 - 550 light-years, generally demarcated by the outer borders of the "Great Houses." Within this region of about 2 million stars, there are approximately 2000 inhabited planets. Periphery – Areas beyond the Inner Sphere, Beyond the Periphery is unexplored space (sometimes called the Deep Periphery)

Age of War - an uninspired name given to a period that was characterized by large-scale warfare throughout the Inner Sphere. Started when the Free Worlds League and Capellan Confederation went to war over the Andurien system.

Battlemech – A type of robotic war machine ranging from 9 to 13 meters in height and with 4 weight classes, Light (20 to 35 tons) Medium (40 to 55 tons) Heavy (60 to 75 tons) and Assault (80 to 100 tons). The term is also sometimes shortened to Mech. Developed in 2439 by the Terran Hegemony, first deployed in 2443, and produced throughout the rest of the Inner Sphere after the Battlemech construction plans were stolen in 2455 by a Lyran Commonwealth covert operations team.

Star League – An attempt to unite the 5 great houses and stop the constant warfare that had plagued the Inner Sphere during the Age of War. Capital located on Terra. Collapsed after the heir to the title First Lord of the Star League and his entire family were killed by Stefan Amaris in a bloody coup, Star League Defense Force General Aleksandr Kerensky lead the retaking of Terra and crushed the usurper. With out a First Lord the League collapsed and was disbanded in 2781

1st and 2nd Succession Wars – all out warfare following the collapse of the Star League characterized by the wholesale annihilation of any targets, civilian or otherwise. Resulted in massive loss of Technological development and almost all existing Jumpships and Warships

3rd Succession War – The Third Succession War began in 2866. It is generally agreed that the war ended in 3025, but fighting continued sporadically until 3028. The years between the beginning of the conflict and the start of the Fourth Succession War were marked with almost constant, but low-intensity, warfare.

LAM, Land Air Mech (taken from Battletech wiki)- Originally conceived during the Star League era, the Land-Air 'Mech, or LAM, is a hybrid military unit capable of transforming between Battlemech and Aerospace Fighter forms, an ability that conveys great speed and flexibility at the cost of power and protection. LAMs are a preferred recon and fast raid unit, but their fragility and rarity made them uncommon in the original SLDF and increasingly so in the Succession War era.

LAM Modes (taken from Battletech wiki)

Battlemech mode

LAMs are essentially Battlemech and act just like other 'Mechs in this mode. Their extra conversion equipment is integrated in the design and does not occupy critical slots. Arm and leg actuators, hip and gyroscope are all treated as part of the LAM transformation mechanism, and hits to these components will impair or prohibit transformation.

Aerospace Fighter mode

In this mode, a LAM operates much like an ordinary Aerospace Fighter. Most importantly, it can operate from Fighter Hangars on Dropships and can make its own way to a target from orbit, where a Battlemech in a drop-pod is a vulnerable and relatively slow moving target. In this mode they have only modest fuel

AirMech mode

As well as Aerospace fighter and Battlemech modes, LAMs have a hybrid interim mode between the other two most frequently referred to as AirMech mode, which resembles an aerospace fighter with arms and legs. In this mode the LAM can move its triple normal jumping distance without generating heat, and has VTOL capabilities.

A/n well that's the updated history and major back story to this fic. My choice to have Athrun and Nicol move to Heliopolis came to me this morning in my half asleep state. The idea of them Cagalli and Kira rounding out a full Mech Lance. The 1st chapter will follow soon so be watching for it.
