My first character was a tiefling rogue/sorceror called Xaxaya (just liked the way it sounded and felt it was a bit infernal), and my current one is a halfling jack-of-all-trades paladin/cleric of Oghma called Sophy (which feels like a good, honest halfling name, but as a suffix derived from Greek can mean knowledge or wisdom so seemed apt even if that's only on Earth and not Toril

). I tend not to bother coming up with last names for my characters, as finding even one I'm happy with is usually difficult enough.
I also started a Durge run and just left the name as "The Dark Urge" (which was then used by the narrator in the intro), but haven't got off the nautiloid with him. I liked the idea he didn't even remember his name, but it'll be cool if leaving the default does mean it gets used by the narrator and others throughout.
