Kailash (Devanagari कैलाश) is the name of a sacred mountain, considered by Hindus to be the home of Lord Shiva. It is a peak in the Gangdisê mountains (part of the Himalayas) in Tibet. Should one circumnavigate Mt. Kailash, all their sins will be forgiven. Should this be done 30 times, they shall be sent straight to Nirvana.
The skill Freikugel in Shin Megami Tensei III: Nocturne, in which the Demi-Fiend conjures a powerful energy blast upon execution may possibly derived from the German Romantic Opera by Carl Maria von Weber, Der Freischütz (lit. The Freeshooter or The Marksman).
