The 'Illusion 100 Skyrim' meme originates from the popular video game, The Elder Scrolls V: Skyrim. This fantasy role-playing game features various skills players can level up, including 'Illusion,' which is part of the game's magic system. When players reach the highest level in any skill, a notification appears on-screen, showing the skill name and level, along with a cosmic blue background. This visual became iconic among Skyrim players and has since been adopted by meme creators to symbolize a scenario where someone has masterfully deceived others, turning mundane fibs into legendary feats of trickery.
