Example Input: Question: What state was the Cheyenne Mountain military complex set in? Passage:The Stargate Command setting was transferred from the fictional military facility located in Creek Mountain, to the Cheyenne Mountain military complex. The unnamed planet from the film was named Abydos in the series and the distance from Earth changed from millions of light-years away (in an entirely different galaxy, "the Kalium galaxy") to becoming the closest planet to Earth with a Stargate, residing in the same galaxy as Earth. Also in SG-1, Stargate travel is limited to the Stargate network in the Milky Way galaxy (unless a tremendous amount of power is used to lengthen the subspace wormhole of a Stargate to another galaxy's Stargate). Ra was the last of an unnamed race in the film, being of a humanoid species with large black eyes and a lack of facial features. In SG-1, Ra is one of many "Goa'uld System Lords," who are a race of parasitic eel-like creatures. There were also changes to the Stargate. The unique set of 39 Stargate symbols in the film were replaced with the concept of 38 symbols that are the same for each Stargate (Earth's symbols based on Earth's constellations), plus a single point of origin symbol that is unique to that individual gate. While the kawoosh effect in the movie was created by filming the actual swirl of water in a glass tube, and looked like a vortex on the back of the Gate; on the TV series this effect was completely created in computer graphics by the Canadian visual effects company Rainmaker. At the beginning of season 9, the original movie wormhole sequence was substituted by a new sequence similar to the one already used on Stargate Atlantis, but being blue as it was in the movie and SG-1, whereas in Atlantis it is green and in Universe, it's white.
