Fledglings are humans in transition to Turning into vampires; they are considered not-yet or newly born. To be 'truly born', they must die, be buried, and successfully dig themselves out of their grave. Upon being reborn, they are immediately in a frenzy for blood and, nearly feral and starving, will be unable to control themselves and will kill anything or anyone close to them just to drink blood. To complete the transformation, they must feed on an exceptional amount of fresh human blood within the next 24 hours, or else they will fade and die.
