Only some versions of the game had the battle this was with, from what I recall. There was a "True Dark Fact" battle after acquiring the sixth book at the top of the tower in the NES version, but when I played the Turbo Grafix 16 and "Chronicles" versions the fight was missing... probably because it flowed directly from Ys I into Ys II in those versions.
Best mix of elements from Over Drive, Protectors, and the full Final Battle.
Didn't know this existed what the fuck, it bangs
