[Warning: long] According to several different source books, the Duchy (Earldom) of Orloff is founded in 2691 based on the Camlan legal precedent whereby worlds capable of autonomy can break away from the larger states within the FWL. The planets Kievanur and Semenyih are the only two worlds of this early Duchy of Orloff. Just two.
YET, the start of the 1st succession war (2786) this micro-Duchy had raised EIGHT regiments (and it raised three more during the 1st succession war). For comparison, provincial forces for the three larger founding states of the FWL are only marginally larger: the Marik Commonwealth (51 Worlds) had 14 regiments (Atrean Dragoons), the Principality of Regulus (40 Worlds) had 11 (Regulan Hussars), the the Duchy of Oriente (31 Worlds) had 16 Regiments (5 Fusiliers and 11 Hussars). Similarly, the Duchy of Andurien has 6 regiments for its 13 Worlds. So, 8 Regiments for just two worlds is an absurd concentration of military build up for such a small region.
But, that is not the best part! Orloff troops are both more experienced and better equipped than just about any other force in the FWLM. The Orloff Grenadiers are the only provincial force to have two Assault weight regiments (for comparison only 2 of the 40 Marik Militias were Assault weight in 2786 and there are only 9 regiments of that weight class in the entire FWLM). Also, Oriente and Orloff forces are given larger bonuses for RAT than the FW Guards, (the premier federal troops). The short form is that the Orloff Grenadiers used the best, most-expensive mechs available and, on average, were among the best trained pilots in the FWL. Again, this all comes from those two worlds: Kievanur and Semenyih. These worlds had to be massively populous and fantastically wealthy to afford this level of military expenditure. Right?!?
This is where the ridiculous story of the early days of the Duchy of Orloff really comes apart. Neither planet is ever given much detail. Semenyih stays around on the map and is never really used as a place of importance in the universe. Moreover, by the end of the 3rd Succession war, Semenyih has left Duchy of Orloff. It would be incredibly odd if Semenyih was properly the home world of the Orloff family and the place from where most of their political and financial power derived. So obviously Kievanur must have been the super wealthy home of the Orloff family. Maybe it was, but it is hard to know as the planet disappeared from the maps during the 2nd succession war with no explanation. So, after raising huge numbers for recruiting and having the capital to form EIGHT top-of-the-line regiments the home worlds of the Duchy of Orloff either die off or turn their back on the state they made?!?!?!? Huh?!?!
This seems like a backstory that desperately needs a good retcon. It can be as simple as having a planet killer meteor take out Kievanur, but some kind of backstory needs to be told here. Are there any chances one of the writers will sort this?
