Lost Legion/Third Legion

The Lost Legion is separated by regiments themselves, which consists of other Legions. Among these chapters is one stationed in Skyrim.

Background
After the end of the Great War and the signing of the White-Gold Concordat, many citizens of the Empire, specifically Nords, were dissatisfied with the terms of the concordat. One of the major terms of the concordat was the banning of the worship of Talos, and Hammerfell being removed as an Imperial Province. However, not only Nords disapproved of this.

Among those who disapproved were a few Legionnaires, who were eventually banished by the Empire, unwilling to risk war with the Thalmor to protect the peace they sought so hard for. Though it is said that what remained of the Lost Legion pushed north to Skyrim, it is later (yet indirectly) revealed that there are other two regiments; One in High Rock, and another in Hammerfell, indicating that the Legion grew overtime.

Society
Unlike it's other fellow regiments, the Skyrim regiment was harsh towards any and all altmer, their patrols ordered to kidnap altmer on sight and have them tortured until death. This method, however, ended with the previous Legate's death and the crowning of Bradas Mjorensssen as it's new Legate, after the latter defeated the former in fair combat. With the new leadership, the future of the Third Legion remains uncertain, but hopes are high that they will gain an upstanding reputation.
