Zeta-15

Oh Lord, this ain't right.
Zeta-15 is a non foundation ex-MTF group consisted of 15 members that defected after being tasked to take some soldiers and hunt down Twain. This resulted in the sacrifice of 3 of it's members. During the ReD's Rest Mission they appear and help ReD take down the remaining members of the foundation, including Patriarch and Nico. A majority of the group of soldiers are killed with the rest of the foundation, bringing the member count down to 6. 2 of these members left the group once the story was complete, choosing to stay in Aermagh. The other 4 members would later join the Decade with Magnus.

Original Members:
All of the members of Zeta-15 had latin names, even before they were in the decade. Their real names are all unknown. Gladio, Deus, and Sidus's bodies can not be found in Aermagh's free roam. The other 6 deceased bodies can be found trapped in ReD's Crystal in ReD's Rest.
