In a medievalesque world similar to our medieval era, the culture is mostly the same, the clothes and religion is similar. But there is a "Darkness" (at night or in very dark places) which forms into "beasts" through some means, and they can be held back by any form of light.



In Brandon Sanderson's "The Way of Kings" for example, plants and animals have shells and carapaces to weather out the storms. I see a problem with luminescent animals in the night, because they'd be easy to spot for predators, even though they might repel the "Darkness."



How would the animal world adapt? Could organisms adapt to emit light or would they have to rely on lantern and torch light?

    How dangerous are those beasts? Can you compare them to, let's say, wolves? How many of those beasts come up in a normal, moon-lit night in the wilderness?

Predators would also have to emit light else they'll be the hunted.



If animals glowed and formed schools or herds, the light would be confusing to predators like the stripes of the zebra.



At the end of the day everything would have to glow else be eaten so it's a level playing field.

    Most organisms in the deep sea don't glow all the time. They emit light only after being touched or disturbed in another way.



    In your world, if "darkness" transforms into "beasts" somehow, simply standing in the dark without emitting light is not harmfull. Standing in the dark and not emitting light while a "dark beast" approached is potentially lethal, so plants and animals might adapt by lighting up only when stressed. Predators and prey alike can hide and hunt in the dark and only light up if a "dark beast" approaches.



    The light is emitted by mixing certain chemicals inside the body or on the outside of the skin, just like in fireflies. These chemicals have to be produced by the body, which takes resources and energy. Not wasting these resources (by lighting up if no "dark beast" in nearby) is beneficial for the survival of the individual and would probably drive evolution in this direction.



    Humans (that cannot emit light) need to light fires or lanterns to protect against these beasts.



    Some animals that cannot produce light might seek shelter near human settlements (like birds, rats and foxes) and others might hide underground (like rabbits, lizards and insects).
