The Samaar Federation is an interstellar federation in Xenoblade Chronicles X. They control a radius of around 6 million light-years of space, spanning multiple galaxies. The Federation is made up of many alien races which have a similar physical composition. The Founders of Samaar were the Samaarians, who came from another universe. It is unclear whether they exist in the current Federation, as Luxaar describes the Human race as the "legacy" of the Samaarians. The Samaar Federation homeland is apparently lost.
