According to the intel, the group they were after was stationed in Gale's Eye under the protection of a First File of Tempest and their soldiers.
A First File was the Tempest equivalent of an Amaharpe General; therefore, they could not be underestimated.
Fortunately for them, in order to avoid drawing too much attention and keep a low profile, despite being under the protection of a First File, their targets would be moving in as a separate contingent not too far behind the main group.
This contingent would be their target. Or, to be more precise, the mages under their guard.
By the time Niflheim finished explaining everything in great detail, the members of the 9th Division were left utterly dumbfounded.
