The most disciplined and effective military force in history, the Imperial Legions preserve the peace and rule of law in the Empire. At need, the legion garrisons can be swiftly mobilized to protect against invasions or internal disorders, but in Vvardenfell District of Morrowind, the local forts help to insure law and order, providing guards to supplement the local guard units of the Temple and Great Houses Hlaalu, Redoran, and Telvanni.
