I thought it might be fun to revive this topic, since the last update was a while ago and I'm curious about it every now and then.
I didn't get "Caelia" from anywhere in particular; it is an actual (although seemingly rare) name, derived from the Latin word for "heaven",
caelus. She was my first character, and when I created her I had no idea of her eventual role, fitting as the name might be for it.
For the curious, I intended the classical pronunciation, KAY-lee-uh, not the ecclesiastical "CHAY-lee-uh."
(And yes, I am seeking help for my Latin addiction, thank you.

)
Her surname, "Sellidan," is something I made up, to discover later that according to ancestry.com, I stole it from some poor family in New York. I didn't use it for her (and I'm not sure I even bothered to think of it) until she became deputy judge of Elvandar, at which point I decided that it would be nice and official-sounding for her to have a surname.
