A Squire From a Knight's Own House?

[DaimosofRedstone]

But don't house Andal-tradition Castles more than one knight, e.g. household knights?
Aren't those able to take on squires?

[Zorbeltuss]

If they can afford it, yeah.

But ideally, you'll want your sons off squiring elsewhere, often for the most prestigious Knight you can find, for reasons explained above.

[DaimosofRedstone]

I know the example i will bring smashes my case because it is so over the top, but technically ALL of the Kingsguards, who are considered archetypically knights, are household knights to the royal family.

[Carriker]

But i think in reality the difference between "been squire at a castle" or "beeing fostered by the house which rules the castle" might not be very big.

But you aren't squired to a castle. You're squired to a specific knight. Where that knight goes, so do you. And the educational focus is different. A fostered boy may be taught to start handling arms, but most of his training is in etiquette, recognizing House heraldry and the like. A squire may or may not be noble, but he's a servant to the knight he serves, exchanging service for training in the arts of war.

[Paedrig]

But at least for a squire of high heritage his service would (or vat least should) incorporate exactly these things - heraldy, manners etc.
Beeing a squire did not only mean learning the arts of war - a knight is much more than this (at least as the ideal which stands behind knighthood). And a squire (at least a noble one) should leanr much more.

Of course beeing a squire of a lowborn knight or even a hedge knight is a whole different thing, but for boys of high heritage...
