Significant Changes from Published Material :
The Imperium :
Ignore all references to The Emperor and The Nobility, substitute the following:
The Emperor
The most powerful entity in known space, this being’s overwhelming goal is maintaining the Status Quo (affectionately known as ‘The Stasis Quo’ to his subjects). Imperial troops (known as Void Troopers) are used only for one goal, and that is to discipline the forces of the Archdukes. Imperial Troops are not deployed from their deep space bases for any other reason, including invasion from beyond the Imperial borders, it is the responsibility of the Archdukes to ensure the Imperial borders integrity.
The Emperor has ruled for well over 200 years, and is obviously immortal, having the entire Imperium’s medical capability at your disposal means that the Emperor would have trouble dying naturally even if it was disposed to do so. The Emperors name is Cleon VI, it’s resources are unimaginable and it has power to match, at this level of power it is no longer even remotely human.
The Nobility
The Archdukes have power and resources second only to The Emperor itself, they have renounced their basic humanity and become something very much both less and more than human. ‘Rich’ is not a term that has relevance to an Archduke, they can draw apon the resources of a Sector and may not be aware of their personal wants, they just are satisfied without any interaction on their part. Archdukes spend their time in a ruthless and Byzantine game of economic, cultural and military game of acquisition from each other. The Archdukes react savagely to any external influence in their games, a reputation that keeps the stagnant Imperiums borders quiet.
The Dukes may be just as alien and inhuman as the rest of the upper nobility, having the power of an entire SubSectors output, their main goal appears to be to become an Archduke, this is generally achieved by assassination or open warfare. Dukes are the most volatile of the Nobility, and often succumb to mortality through the machinations of each other, this constant warfare is the cause of most of the woes of The Emperors subjects.
The Lesser Nobility are more or less human to a large extent, although they may display a characteristic lack of human consideration for their fellow beings, their activity is a mirror of the Greater Nobility drawn on a smaller scale.
Knights all belong to a specific order, which in turn is generally dominated by a particular noble house, all military units must be commanded by at least a Knight. Only Barons and above can Knight a commoner, and generally reserve this honour for those within their own households, The Emperor can bestow Knighthood apon any of his subjects of course, and reserves this for useful bureaocrats or other functionaries.
Nobles may not be molested by commoners, regardless of the situation, and Nobles may only inflict bodily harm apon each other with melee weapons. Considerable R&D is spent on making melee weapons more effective against modern armour types due to this particular edict.
The Armed Forces:
The Army, Marines and Navy have a different character to standard MegaTraveller, and generally conform to the following ‘classes’
Imperial Void Legions (TL 15)
Noble House troops (TL14)
Monastic Warrior Orders (TL12-14)
Condottiere (TL10-14)
Planetary/System troops (Any TL less than 15)
Imperial Technology Restrictions :
The Imperium reserves the right to mandate Technology Zones, technology embargoes thinly disguised as altruistic programs under the ‘gradual assimilation’ banner, a method of coercing planetary governments to toe the Imperial Line. This has had many strange effects, the methods of policing the TZ’s are unknown and appear to be applied unevenly, but the consequences of transgressing are severe. The Emperor can put in place the Imperial Interdict on what is considered a defiant system, all interstellar trade is prohibited and Noble House forces blockade the system to enforce this. A byproduct of the Imperial Interdict is an invariable and total economic collapse of the proscribed system, even if the system seems to be economically independent on the surface.
The Imperium actively discourages communication between systems and jealously guards it’s control over the X-Boat communication network, this maintains it’s power over information transfer (and the possibility of manipulating that data) and effectively controls the intersystem economy.
Due to the whimsical and apparently haphazard enforcement of TZs, many systems have passed Sumptuary Laws, a series of restrictions on the apparent sophistication of normal items which sees modern laser systems utilising wood, leather and decorative metals in the housings. This is balanced by the desire for higher TL equipment and the prestige that goes with owning such exotic items.
Health and Ageing
At TL 14, the Imperiums ability to heal and maintain a healthy body is amazing. Human citizens can expect to look healthy and fit up until about 110 years old, when the non-oxidisation techniques cease to function on their cells, until then they look, feel and are about
30 years old for a TL 9 Human.
Cybernetic (biological or synthetic) Enhancement
Extreme exercise and dieting regimes, intense study and nonstop training can only do so much. At some point, biological engineers have to intervene directly and reshape the body and mind to allow extremes of performance. Many citizens are uncomfortable with this, but at TL 14 the modifications are rarely extreme enough to be noticable as those of earlier TLs.
Any Statistic that is ‘C’ or higher is the result of cybernetic intervention, excluding Social Status ranks. Some basic techniques are:
Muscle Interweaves
Reflex Boosters
Cardio-Vascular rebuilds
Synaptic ‘greasing’
Memory Implants and storage boosting
Many more are available, and some have better reputations than others.
