Emperor
Corrino (Adrian Sparks) has issued a challenge that the House which can produce the most
spice will control its source, the
desert planet Dune, with no rules as to how the Houses can achieve this goal. Meanwhile, Lady Elara (
Musetta Vander) of the Bene Gesserit and bound
concubine to the Emperor, secretly takes the "commander" - the player - into one of the Heighliners, a person whose bloodline and future the Sisterhood had checked. According to Elara, they saw many visions of the commander dying — and only in one vision does the commander live and even rise to control massive armies and bring peace to Arrakis; thus, she and the Bene Gesserit have betrayed the Emperor's trust to bring about this possible future. As in
Dune II, the three main playable factions are
House Atreides,
House Harkonnen and
House Ordos. There are also four non-playable subfactions: House Corrino, the
Fremen, the Mercenaries and the Smugglers. ;House Atreides :Hailing from the water-planet of
Caladan, the noble Atreides have a strict loyalty to their Duke and follow him with zeal. The Duke's famous
Mentat, Noree Moneo (
John Rhys-Davies), advises and resides over the Duke's forces on Arrakis. The House's fleets of
ornithopters ensure their superior air power backed by Sonic Tanks to humanely destroy enemies. The Duke also wishes to develop an alliance with the Fremen, the native warriors of Dune. ;House Harkonnen :The Harkonnens are ruled by the wicked Baron and come from the volcanic waste-planet of
Giedi Prime. According to Lady Elara, the only thing human about the Harkonnen is their genetic makeup, as all humanity was abandoned long ago in favor of brutality and maliciousness, favoring pure firepower brought by Devastator Tanks and the Death Hand Missile. The Baron's Mentat, Hayt De Vries (Robert Carin), was born from the flesh of a dead man in the
Tleilaxu Flesh Vats. ;House Ordos :The Ordos originate from a frigid, ice-covered planet unnamed in
Dune 2000 but later called Sigma Draconis IV in
Emperor: Battle for Dune. As they import their goods from nearby star systems, House Ordos relies on their skills as merchants to survive; however, their wealth has made them increasingly paranoid. According to the manual, House Ordos buys all of its units instead of constructing them themselves, including Saboteurs to demolish buildings and Deviator Tanks to temporarily turn enemy vehicles against each other. Unlike the other two houses, House Ordos is not mentioned in any of
Frank Herbert's
Dune novels, but it is mentioned in the non-
canon The Dune Encyclopedia. ==Development==
