You did read the outline! I'm touched.
And yes. The Fates were never named as such in the game (post-apocalyptic wanderers not having a great base of classical learning), but the Queen in Black was Clotho. The Queen in White was Atropos, and the Queen in Red was Lachesis.
There was a wonderful moment early in the campaign when Domino, a Chopper and the previous character of Eileen's player, was confronted by the three in a dream, each of whom offered him great rewards if he supported them. Looking back, I'm not sure if the GM had already decided that the enemies were going to be the Fates, or if the retroactive allusion to the Golden Apple was just happy coincidence. In any case, Domino declared his intentions to forge his own path, turned his back on all of them, and walked away in the dream. Defining character moment for both Domino and the player.
Mekken and the Buzzards killed Artemis. They were all partially robotic, having gone through Zig-Zag's 'procedures'. Honestly that was a low point for the campaign- Artemis' player was clearly not feeling it that night, and literally had Artemis jump on Mekken's back 'like a horsey' to piss him off enough that he would kill her.
