Rose Trevelyan has an older (biological, not adopted) sister, Calla (a name I chose 1) because I wanted them both to have flower names and 2) because the consonant-vowel-consonant-consonant-vowel pattern is the same as Tyrra’s–if y stands in as a vowel.). She hasn’t appeared physically in any fic so far, though she’s mentioned in Letters Home. She’s about four years older, married, toddler and a baby, stable and dedicated and will one day make a marvelous Bann. Her parents are baffled at how someone so responsible and law-abiding came from them, but of course they love her beyond words.
Rose idolized her sister, growing up. She’d tell anyone she met how smart and funny and nice and perfect her big sister was. She’d crawl in bed with Calla when she had bad dreams before she’d go to her parents. For a while, she named all her dolls ‘Calla’ because Calla was the best everything. Why name a doll anything else?
Calla likes to make order from disorder. She and Josephine, I think, would get on like houses on fire. She takes the responsibility of her position very seriously. She’s not a stick in the mud, though. She’d never admit it, but she gets a thrill from Rose’s practical jokes, and some of the best ones started as ideas she casually planted and let Rose believe were her own. When it came time to do weapons training (every Trevelyan does weapons training), her parents expected their tall, willowy daughter to make a half-hearted effort at archery before wheedling out of practice altogether.
They were wrong. Oh, Calla can use a bow, but she’s such an accomplished sword-and-shield warrior that Rose still insists she ought to compete in tourneys. Calla smiles and shakes her head. (She doesn’t tell them–any of them–that she did compete the year after her sister was taken to the Circle, and could have gone all the way, but didn’t want to risk being recognized. Didn’t want to answer for herself. Wanted to stay anonymous. It was a hard year, that year.)
Calla rides alone often. She says she likes the solitude to think. Perhaps coincidentally, her lands are never plagued by banditry. Ever. (She’s more the child of her parents than they even realize.)
