The show begins with the lights around Mediterranean Harbor darkening, and a pre-show musical portion plays while mist blows across the lagoon.
As the pre-show ends, a horn call is heard, and spotlights form a large pentagram in the sky.
Mickey is dressed as a sea prince, with a flowing robe, a crown of large golden tasseled feathers, and a trident.
An aggressive drumbeat and thunder sound ring out as fireworks launch from Mount Prometheus, the volcano located adjacent to Mediterranean Harbor.
The sound of male chanting, representing the voice of the Fire Spirit Prometeo, rings out as he emerges from under the water in the form of a mechanical phoenix.
Bellisea starts to move toward him, water streaming from her barge as fire flickers in unison from Prometeo's wings.
Prometeo's fiery wings change to curtains of sparks and his body sparkles with blue lights, and Bellisea launches fireworks from her barge.
Immediately following, the ending song "Swept Away" plays as Bellisea and Prometeo remain on the water, before finally vanishing from sight.
Concept development began when Oriental Land Company show producer Koichi Sasamoto and his staff contacted French event designer ECA2 and Yves Pépin to brainstorm ideas.
[2] On the Walt Disney Creative Entertainment end, John Haupt served as the producer, while Thomas Tryon was the production manager.
After deciding on the elemental love story concept, Sasamoto's team went to France to work out the practical effects details.
[3] Sasamoto's team then moved to Valencia, Spain where they visited a fireworks factory and built and tested a full-scale Prometeo prototype.
After completing testing, Sasamoto returned to Japan and oversaw construction of the show-use Prometeo, which was manufactured by a firm specializing in precision machinery.
After manufacturing, the show-use Prometeo was tested for 2 months in water conditions and installed in a 6-meter deep pit, which was constructed in the Mediterranean Harbor lagoon.
It was also the first to use a wireless LAN to handle all show communications, including lighting, fountain, and pyrotechnic controls.
The use of wireless LAN was made possible by the lack of competing radio frequencies at the Tokyo Disney Resort.
Greenaway had previously composed the music for the Disney fireworks show IllumiNations: Reflections of Earth and parade Tapestry of Nations, both performed at Epcot.
The vocals of the main show and "Swept Away" were recorded and mixed at the O'Henry Sound Studios in Burbank, California by Vicari.
A Japanese-language version was also created but was only used during the Tokyo DisneySea Season of Hearts promotional period, from February 14 to March 14, 2007.
