One of my early readers, reading Pastiche, asked me “Did Giles and Richard know each other before the War?”
(Giles being Major Giles Lefton, hero of Wards of the Roses, and Richard being Lord Richard Edgarton, who appears in Wards of the Roses and On The Bias, and who gets the story of his own romance coming up in Pastiche.)
They’re both upper class, well-educated, competently magical men in a relatively small community, so yes, they’ve been moving in similar circles for a good while.
They are, however, a generation apart in age.
Albion is not a massive community. Sparing you my spreadsheet of demographics for the moment, the community is roughly 250,000 people in the 1920s. There are about 200 families who hold a title (usually Lord of the Land ) and probably another 300 or so who are upper class and possibly of the minor aristocracy (cadet branches of the titled family lines, and so on.)
(Those aren’t the only positions of power, of course. The Mysterious Power series will be getting more into some of that.)
Their families: Richard, obviously, has a title, and comes from one of the noble families. Giles doesn’t, but comes from the minor aristocracy. His family have multiple properties. He’s well off enough personally that money is not an issue for him. They were both in Fox House at Schola, so they share at least one club, and probably more than that one.
They certainly have run into each other at various social events (such as the Temple of Healing garden parties, a major source of fundraising for the Temple). An amicable but distant sort of acquaintanceship.
When did they meet? I suspect they didn’t know each other terribly well until Richard – or someone else Richard knows in the Guard – needed Giles and his mathematical brain for a spot of code-breaking. At that point, of course, these two intelligent, practical men would find common cause pretty quickly. It’s a relief when you find someone competent who can do the thing you need to solve the problem at hand without fussing.
I am quite sure that was before Giles became blind, however. Richard is, at times, still figuring out how to handle some of that smoothly, in a way that wouldn’t be as true if they’d only met after that point.
I’d guess they met sometime in 1913 or 1914, in the buildup to the War, but I haven’t pinned that down yet.
 Yes, women can have the equivalent position, though most families inherit via male primogeniture if that’s an option. I do plan to talk about this in more detail sometime!
