Spriggan 12

The Spriggan 12 (スプリガン１２ Supurigan Tuerubu) is an elite unit serving as Emperor Spriggan's (the emperor of the Alvarez Empire) personal guard.

Overview
According to Hyberion, the members of the Spriggan 12 (dubbed "Shields") are extremely skilled and powerful Mages, and around the same level of power as God Serena: the strongest Mage from Ishgar. The Spriggans also appear to do whatever it is they please and roam about, as when Zeref asked member Invel to gather the other eleven members, he noted that such a task on such short notice would be extremely difficult. Some also appear to operate independently of Zeref's wishes and act of their own accord, as Zeref said that the Alvarez invasion of Ishgar in X781 was due to some members of the Spriggan 12 not following his orders to stay away from the continent.
