Immortality — Tag Meaning
Examines living forever as condition rather than power: immortals loving mortals on borrowed time, pairs of undying watching centuries together, or the newly deathless discovering what the price actually is. Fandom's treatment is overwhelmingly elegiac — immortality fics are about loss with the timeline stretched until it sings.
What to Expect From "Immortality" Fics

Alternate Universe - Vampire
Turns one or more characters into vampires in a canon that didn't have them, or rebuilds the whole setting around vampire society.

Reincarnation
Carries souls across deaths into new lives, with memory as the variable that defines each fic: full recall, fragments surfacing through dreams, or recognition without understanding.

Alternate Universe - Gods & Goddesses
Elevates characters to divinity — gods of death and harvest, rival pantheons, mortals who catch an immortal's eye. Writers either invent fresh mythologies or rework existing ones, and the genre's central pleasures are worship as intimacy and the catastrophic imbalance of a god in love with something that can die.

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.
