full_context: Document 1: Illyria (Angel): Illyria is a fictional character created by Joss Whedon for the television series "Angel". The character is portrayed by Amy Acker. She is a regular during the last third of season five. The character is introduced in a story where main character Fred Burkle dies of a mysterious infection, after which her dead body becomes the host of an ancient demon, Illyria, who once ruled the world but now finds she has outlived her kingdom. Subsequent episodes featuring Illyria document her struggle with adapting to the human condition, Fred's memories, and the continuing grief of Fred's friends and loved ones, who make up the central cast of the show. "Illyria raises significant questions about how essence and existence are related. This is central to understanding existentialism. Whedon raises many challenges to existentialism through Illyria's journey—from the point when she pops into existence at Fred's death, to when she 'performs Fred' as Wesley dies."
