No viable military perks means we can't really build toward that. Liberal gives us more freedome, and overbearing turns out to have been a bigger cost than anticipated for the points. That said, we're still making good use of lesser title and tutors, so the only potential waste is liberal, which I still expect to benefit us in the long run even if it hurts us a bit in tandem with overbearing in the immediate future.
The GM just said that these are just the traits you start out with and that most of the character's skillset will be determined by the actual game.
And though I don't really like the idea myself, there are in fact several traits that'd help towards a military route and being naturally talented at the fighting itself is not actually required to get good at it.
For example, you could just go:
Power At Any Cost [20] - Maximises the likelyhood that the secret leads to open battle, where the warrior princess' skillset can fully come into play.
'Terrible Accident' [-10] - More points and again increases the likelyhood of an open confrontation.
People's Princess [20] - Popular support is important to make our accusations stick and to get a bunch of enraged non-nobles to help put those demonic bastards down.
Mature [20] - Being taken seriously is as important for the same reasons, though more directed at other powerful players.
Inspiring [20] - And so is being a rallying point, not to mention that being a warrior rpincess isn't all about wading into battle personally.
Impassioned [-10] - Need the points and quite frankly the bleedover may in fact hurt the guy making secret deals with demons more than the forthright and righteous warrior princess.
Handsome [-20] - Need the points and this is not
as useful for a man as the others options while the bleedover is nice.
Optional and a bit risky:
Bloodknight for the bleedover bonus and to make him some more enemies and in the hope that we'll have enough of a number advantage to still put him and whatever demonic powers he gets down in the final confrontation.
Would most likely use those points to buy another bonus (either attractiveness to increase the appeal to the masses and make us an even better figurehead in the fight against everything demonic or to Charming for more stronger personal connections).
Alltogether, you'd get a bonus to almost everything you need to trigger the climactic battle against our brother with a reasonable amount of forces on our side at all which means you can spend more time pumping up the actual combat stats during the game itself.
