Isolation — Tag Meaning
Covers both circumstance and feeling: characters cut off by quarantine, exile, secrecy, or psychology. It can flag a plot device (snowed in, stranded) or a darker exploration of what being truly alone does to a person, so surrounding tags determine the temperature.
What to Expect From "Isolation" Fics
Separation from the world as a central pressure — sometimes cozy (two people, one cabin), sometimes genuinely bleak.

Loneliness
An emotional-core tag for fic steeped in isolation — characters who are surrounded by people yet unseen, or literally alone and feeling it. Authors use it to mark melancholy character pieces, and the loneliness usually exists to be answered, eventually, by connection.

Huddling For Warmth
The canonical companion to body-heat sharing, with emphasis on the huddle: characters pressed together against the cold in caves, tents, stalled cars, and unheated safehouses. One of fandom's oldest tropes, it weaponizes weather in the service of intimacy.

Angst
One of the foundational tags of fanfiction, covering stories centered on emotional pain — grief, longing, guilt, heartbreak, despair. Unlike a content warning, Angst describes mood: the fic dwells in difficult feelings and wants you to feel them too. It says nothing on its own about whether things improve.

Psychological Horror
Horror that works on the mind rather than the body: paranoia, gaslighting, unreliable perception, the slow erosion of a character's grip on reality. Authors choose it over plain Horror to signal that the scares come from dread and disorientation, not monsters or gore.
