Krampus (Better Watch Out)

The Krampus was created on 5 December in Salzburg by a vagabond in fulfilment of Maria Werner's wish that the mythical Krampus be real. (AUDIO: Fairytale of Salzburg) He commanded an army of imps who collected all Salzburgians in order to send them through the gates of hell created with the Krampus. (AUDIO: Better Watch Out / Fairytale of Salzburg) Unlike the mythical Krampus, this creation was as tall as the mountains. (AUDIO: Better Watch Out) He was defeated after Helen Sinclair brought the historical Nicholas, bishop of Myra, from the 4th century Asia Minor to confront him, in accordance with the myth of the Krampus. Thus, Helen saved all Salzburgians, as well as the Eighth Doctor and Liv Chenka. (AUDIO: Fairytale of Salzburg)
