Garlean legions and previous FFs

[Fenral]

Dalmasca of XII was a nation at war with the Archadian Empire. Dalmasca eventually fell due to the machinations of Archadian subterfuge, most notably spying.

Technically, the real war was between Archadia and Rozzaria. Dalmasca had the unfortunate distinction of being a neutral territory on the land-bridge separating the two, kind of how Ala Mhigo is relative to greater Eorzea.

If I recall rightly, the "yae" title is that of a Garlean royal who is not eligible for the throne. Zenos yae Galvus, then, fits that description.

None can say for sure whether or not he participated in the war of succession, gave up his claim to the throne to be spared, or was never eligible in the first place. We literally know nothing of Zenos yae Galvus except his appearance, name, title, and rank - Legatus of the XIIth Legion, appointed viceroy of Ala Mhigo after van Baelsar's death / desertion, and a member of the royal family ineligible for the throne. (Hell, in-universe we don't even know his name!) According to the (False) Griffin he's much worse as viceroy than van Baelsar was, but... given the Griffin's heavily biased, how true that actually is remains quite suspect.
