The Others

"They're coming. Our enemy doesn't tire — doesn't stop — doesn't feel."

The Others, commonly known as white walkers, and also called cold gods and white shadows, were a species of supposed and    hailing from the Land of Always Winter. The Others were humanoid and were distinguished by their piercing eyes and blue-white skin, as well as their ability to command legions of the undead through some manner of necromancy. Little else is known about the Others, save that the people of Westeros viewed them as evil monsters. They were thought extinct, or, at the very least, vanquished, after the Long Night.

Biology and appearance
The Others were tall, gaunt, and humanoid, with blue-white flesh pulled tight over their bony frames. Their eyes were universally blue, but are crystalline in appearance, causing them to be compared to blue s. They had pale blue blood and bones that resemble. Not all Others had hair, but those that did had white, long hair. Those others that became Night's King have a crown of ice horns rather than hair on their heads; though, the first Night's King had a beard of white hair.

The Others, commonly called "white walkers" by the people of Westeros, were associated with due to their ability to create wights by resurrecting the dead. Some believed the Others themselves were, but this was a common misconception. The Others were living beings, though they experienced a form of.

The Others are a nocturnal species and only come out at. They also went lightly on snow and left no footprints in their wake, making them nearly impossible to track. Uniquely to them, the presence of Others had a noticeable effect on the environment. For instance, they were accompanied by a terrible cold, and large groups of them moving at once could bring with them a. Oddly, and unlike their wights, they are immune to fire, but weak against dragonglass and dragonsteel.

Reproduction
How Others reproduce was entirely a mystery, much like their origins. They appeared for the first time during the Long Night the furthest north of Westeros, hinting that they were indeed a self-sustaining species before they were introduced to Men. However, Night's King had the ability to turn human infants into Others by touching them. Indeed, the second Night's King was a human himself and was, originally, one of the First Men.
