4. Wights And White Walkers Are The Same
This has been a source of confusion for many book readers for a long time, even before HBO's TV show. The distinction is possibly explained better on the show because the creators can visually illustrate what the two look like. The White Walkers (also called the Others in the books) are mysterious and eerie sorcerers who are only talked about in quiet rumors and stories. Even in the literature, very little is understood about them at this point, except for the fact that they could be very harmful. The Wights are the more frequently observed deceased individuals (or animals) that the White Walkers have revived. In essence, they are senseless zombies, manipulated by the Walkers that brought them back to life. Although fire can destroy the Wights, it has always been a mystery how to defeat a White Walker. This is why Sam's ability to kill one was considered a significant achievement. Sam accidentally found out that weapons made from Obsidian (also known as Dragonglass) could harm the White Walkers.
