Freeblade Knights are Nobles that have left their House for whatever reason and take their Knight with them. This is a cool idea that also gives people the opportunity to model and paint up a single Knight to add to their army. And it's obviously based on the Knights Errant of the Middle Ages. But unlike then when a single man could maintain all his weapons and armor himself so wandering around was an option a Knight isn't a one man operation.
A machine the size of a Knight is going to need maintenance as well as repair after a battle. Does the Freeblade take a retinue of Sacristians along with him? Unless they're near to Mechanicus forces or another Knight house where do they get the parts? Or if they're so easy to maintain why do they need the elaborate Keeps the Houses use, unless it's just tradition? And what about ammunition? The Errant pattern at least only uses common Heavy Stubber rounds. The Paladin could possibly get ammunition from a Guard armored regiment, assuming the Battle Cannon rounds are compatible. And the ones that are left behind on planets after a battle, who reprints the thing in the new Freeblade colors? That's got to be like repainting an entire house solo.
And how do they travel if they're not on their home planet? Does the House they're leaving give them a lift off world? Or if they attach themselves to a crusade or regiment do they just hope there's a heavy lift ship available for them?
I like the Knights and the idea of Freeblades. I'm just wondering if the answers to my questions have been said somewhere I've missed.
