Twilight is the light from the sky between full night and sunrise or between sunset and full night. When regarding to World of Warcraft lore, twilight magic seems to be a combination of Light and Shadow. Light and Shadow are the most fundamental forces in existence. Although contradictory by their very nature, they are bound together on a cosmic scale. One cannot exist without the other.
In the twilight, you will find all manner of contradiction.
