Cydalise et le Chèvre-pied Cydalise et le Chèvre-pied Cydalise et le chèvre-pied ("Cydalise and the goat-foot" or "Cydalise and the satyr") is a two-act ballet originally choreographed by Léo Staats to a score by Gabriel Pierné. The libretto was written by Gaston Arman de Caillavet and Robert de Flers, based on Remy de Gourmont's "Lettre d'un satyre". Though it was composed between 1914 and 14 February 1915, its Paris Opera premiere was delayed due to the conditions of World War I until 15 January 1923. The use of the French term "chèvre-pied" (goat foot) to refer to the satyr is distinct to this composition.
Xenosaga: Pied Piper Monolith Soft handled the story development. External studio Tom Create helped develop the game. The creation of "Pied Piper" formed part of a move by the newly-established lead developers of "Xenosaga" to expand the series into other media following the release of "Episode I". The game's script was co-written by series creators Tetsuya Takahashi and his wife Soraya Saga. "Pied Piper" was Saga's last contribution to the "Xenosaga" series prior to leaving the project in 2005. The game's title is a reference to the German fable of the Pied Piper of Hamelin. "Pied Piper" was first announced in July 2004.
