7 (2004) brought a more global approach to the scenario when the Stargate Program was revealed to over a dozen nations, which further helped the international appeal of Stargate SG-1. Alliance of four great races SG-1 learns in season 1's "The Torment of Tantalus" that although most known habitable planets in the Stargate universe are populated by humans, there was once an Alliance of four great races. In season 2's "The Fifth Race", the Asgard tell Jack O'Neill that this strategic alliance had consisted of the Ancients, the Asgard, the Furlings, and the Nox, and that the humans from Earth had taken the first steps towards becoming "the Fifth Race". (This comes full circle in the Stargate SG-1 finale "Unending", when Thor declares the humans from Earth the Fifth Race.) SG-1 had encountered the Nox in season 1's "The Nox", a fairy-like people that wants nothing to do with humanity, viewing them as "young" and having "much to learn". The Nox can live to be hundreds of years old and have a great desire for wisdom and understanding. They are extreme pacifists and never employ violence for any reason, even to defend themselves. Although they outwardly seem to be primitive forest-dwellers, they possess superhuman intelligence and advanced technology beyond that of the Goa'uld, including a floating city. As they have the ability to render themselves and other objects invisible and intangible, as well as the ability to resurrect the dead, they never need to fight. The Nox also appear in "Enigma" and "Pretense". However, Stargate SG-1 revealed virtually nothing about the Furlings, beside making them the story backdrop of an abandoned site in season 6's "Paradise Lost". Furling skeletons were originally planned to be featured in the episode, but the production of such proved to be too expensive. Jack O'Neill concludes that the Furlings must be cute and cuddly creatures, based solely on their name. In "Citizen Joe", another character equates the Furlings to Ewoks based on their name. The length of time that the Furling nature remained a mystery in the series turned into a running gag. When Executive Producer Robert C. Cooper was asked "Will we ever meet the Furlings?", his answer was "Who says we haven't?". The writers later went on to state that apart from showing Furling technology and legacy, no member of the Furling race has ever appeared on the show. Producer Joseph Mallozzi claimed
