La última batalla
Tash is an incidental character during "The Horse and His Boy", but becomes an important character during the narrative of "The Last Battle" when he "follows his worshippers into Narnia." Michael Ward notes that Tash's arrival in Narnia is part of the "deadly atmosphere" pervading "The Last Battle." "At the appearance of Tash, Puzzle complains, 'It's so cold." However other commentators view the introduction of Tash in "The Last Battle" as a type of "deus ex machina", "swooping in from left-field" to threaten Narnia.
