Cornelius "Kernel" Fleck is the main protagonist of Demon Thief, the second book of the series The Demonata by Darren Shan, and one of the three main characters in the series. The name "Kernel" was given as it is the closest he could pronounce his real name, Cornelius, when he was young. Kernel is the host of The Eye which gives him the ability, and the only one, to see patches of lights in the sky and slot them to create Window within short periods of time without spells. His character ostensibly shows chronic depression, solitude, and loneliness throughout the series. Although he hides his shattered emotions under cold, indifferent expression. Contrast with Grubbs Grady, Lord Loss once stated Kernel as a wise person, and occasionally shows his brief sympathy toward him.
