Familiars — Tag Meaning
Pairs magic-users with bonded animal companions — cats with opinions, ravens with errands, creatures whose form says something pointed about their witch. Fanfic's favorite complication makes the familiar a transformed person or a character in disguise, and the witch-familiar bond itself often shadows the romantic one, daemon-style.
What to Expect From "Familiars" Fics
Magical animal companionship with personality to spare; if the cat seems too knowing, it's because it is.

Alternate Universe - Magic
Adds magic to a mundane canon or rebuilds the setting around spellcraft — covens, magical academies, hedge witches in modern apartments. Broader than the fantasy tag, it covers any 'what if they could do magic' premise, and authors often give each character a signature discipline that comments on their canon self.

Alternate Universe - Daemons
Borrows the daemon concept from Philip Pullman's His Dark Materials: every person's soul lives outside their body as a talking animal companion that settles into a fixed form at adulthood. Fandoms adore the device because choosing each character's daemon is an act of interpretation, and touching someone else's daemon is the setting's ultimate intimacy taboo.
