Lol, I had to do a double-take, because I've got Garth Nix's Abhorsen trilogy within arms reach right now and never managed to get into Supernatural 🤣 "What? Sabriel? In Supernatural fic? I mean, I'm not saying it couldn't happen, but for it to be anything like common—oh right, one of the main two is Sam and the angel Gabriel enters later on. Never mind."
