Lots of world building. Author basically creates (what is left of) the entire griffon civilization from whole cloth, with some parallels to Gothic tribes from the days of the end of the Roman Empire.
In the first story, Gilda is presented as a screwup with an unrepentant Darwinist/racist asshole for a father (by which I mean Big Mac's father in Macintosh would win a medal by comparison, though Gilda's father never becomes an unbelievable character). Dash is her only friend, and Gilda hates the fact that they aren't as close as she wishes they were. Story starts three days before Griffon The Brush-Off, goes on throughout the events of the episode and ends a day or two later. Gilda in the story isn't quite what I would call an outright bitch (though she still is extremely caustic towards everyone who isn't Dash) so much as she is exceedingly short-tempered at everyone she comes in contact with (except Dash). Her temper and cynicism leads to the events of Griffon the Brush-Off and the immediate fallout. Story is told from the first person.
