Major General Gärtner (ゲルトナー, Gerutonaa) was the commanding officer that was sent to Briggs by Central Command to call for Major General Armstrong to report to Central so she could be questioned about the whereabouts of Lt. General Raven. In her absence, he was given full command of Fort Briggs. His role was to assist in creating a crest of blood as part of the Nationwide Transmutation Circle, but the forces of Briggs' will proved too strong.
