FFXIV deviates from V, in that IIRC, isn't Alte Roite actually the name of the sorceror bosses you fight in the Interdimensional Castle dungeons? They transform into Jura Aevis dragons when you kill them, making it a two part fight.

(In V, this is the same area in which you also fight Twintania, Catastrophe, and Halicarnassus.)
