The Spriggan 12 is a elite group of mages that act as Zeref Dragneel personal guard in the Alvarez Empire. They are the secondary antagonists in the manga/anime Fairy Tail.
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 Shields also appear to do whatever it is they please and roam about, being that it is extremely rare all twelve are in the same location.
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 due to some not able to attend, while some purposely deny the summons. 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.
In regards to His Majesty, the 12s hold a respectful tone but can be informal when addressing him, while some can hold him accountable for his own actions. Among the 12 the camaraderie is noticeable, with examples being the mutual friendship shown between each other to the respect level given to one another denoted by honorifics.
