Ys 4 vita ending questions

[badluck14]

So some stuff to clarify....
i read online that Ernst was Friedas ex fiancee and garudas brother. I know it was very mildly hinted at ingame, but was there more concrete evidence found in or outside of this game or its sequels?
geis didn't seem like the type to fall into power temptations. I remember him saying he chased his bro to recover the sword, but in this game it made it seem like garuda persuaded both of them to join his cause. And neither brother ever mentioned a third brother in Ys 6 or 7...
also, in adols memories it said he got the travelling idea from his dad, but i remember in the first two games it was mentioned somewhere that it was his grandpa who raised and influenced him?

Not sure where you read the whole Gruda thing.

Ernst is Frieda's ex-fiancee. This is backed up by Nina who is a fairy created by Ernst similar to Jue, Sera and Xisa, and how they mention that Ernst was banished because he stole something (The Black Key in Napishtim) and how his brother (Geis) also left the village.

The one thing Ernst, Frieda, Geis and Gruda have in common is that they are all from the Clan of Darkness. From Ark of Napishtim and hinted in Ys Origin, the clan is formed by descendants of those who tried to control the Eldeen's power by opening the Ark, releasing the Galbas (Wandering Calamity) and pretty much everything that went wrong in the series lore.

I got the garuda thing from an in game conversation. They said garuda convinced a couple ppl to follow his ideals and leave the village, one of whom was his brother, who happened to be friedas fiance, which was one of the reasons why frieda dislikes garuda. I was just wondering what evidence was there in any of the games to support that ernst was that fiance. I know the homunculus one, but i did not remember anyone talking bout the black key explicitly. If they only mentioned is as a "treasure/artifact" that was stolen when the group left, without even hinting what it was or does, then its no wonder i did not connect it.

These are the things the game revealed as I played:

- Guruda is not related to Ernst, or Geis. All they have in common is that they come from the same village;

- Technically-speaking, only Guruda is from the Clan of Darkness AKA part of the Darklings. Ernst and Geis simply were descendants of the original Darklings, like Guruda. It's just that Guruda decided to follow their previous wrong ways, as well as use for himself their old name.
Ernst decided to follow their old ways too, except he didn't seem to bother for the name. He also did the things he did for himself and for his descendants' wishes, unlike Guruda, whom Falcom decided it'd make more sense for some reason to suddenly make him state that all along he just wanted to test humanity, rather than live up to the Darkling's greed, completely contradicting most of the points he had made throughout the game, as that isn't at all the desires of a Darkling, yet he revived the name and used it on himself. Falcom likely pulled that out of their asses the last second before release, honestly, as opposed to just leaving him wanting to attain ultimate power, like all the Darklings would, and how the original Guruda was written for all Ys IVs;

- Technically, Nina, Jue, Xisa and Sera aren't fairies: they are homunculi. This is important to remember, because no fairy is humanly-generated, while homunculi are (although one can still debate that homunculi would be expected to look and act differently from what they do in Ys VI onwards). They are creations of either magic, alchemy or both. I forgot which exactly, if it was ever even explained or hinted at.
Ys VI PS2 and PSP's konami translation got that right, while XSEED's Ys SEVEN and YsC didn't, so it's no surprise people would be confused. The kanji used for those 4 characters and YsOnline's homunculus system, as far as I remember, could indeed be translated to either "homunculus" or "fairy", yes. But the definition of a fairy excludes "fairy" being a possible translation for the term given the context of the games, thus leaving us with "homunculus" ("homunculi" for plural);

- Yeah, Ernst was Frieda's ex-whatever (never stated whether fiancee or boyfriend or boytoy etc., but it was made clear it was one of those), who left to grant his own wishes of taking over the world and attaining ultimate power, the power of the gods (the eldeen) and their wings. And for that, took the Black Key with him that we see in Ys VI.
