ecclesia age

Order of Ecclesia does NOT happen early in the 19th century, but more to the middle. To start the explanation, let's recap OoE's intro, shall we:

Now, to begin:

"But, EARLY in the 19th century, having lost their ability to resist the darkness, those in positions of power AT THE TIME began to search for new ways to counter Dracula."

So, early in the 19th century I assume to be from 1800 to 1830s. However, according to Igarashi, Richter disappeared "not too long after SotN" therefore causing humanity to become unable to resist the darkness. "Not too long after SotN" can't be twenty-thirty freaking years later, dude. So let's reduce that to 1810s, tops. Time enough for the Belmonts to disappear and for the people to notice the Belmonts are gone, for new organizations to rise to fight Dracula, all while staying inside the "not too long after SotN" and the "Early in the 19th century" range.

"Our organization, Ecclesia, was BORN THEN as one of those countermeasures."

See, that's the best part. It says RIGHT HERE that Ecclesia was born THEN, past tense, during the early 1800s, as one of the countermeasures. This line right here should be enough to prove the point.
But let's press on:

"Many organizations were established with the same goal, and say after day, they conducted their studies diligently, but each was dissolved when they failed to produce satisfactory results."

So, how long do you think it would take each of these organizations to appear, try to prove themselves, AND disappear? We're not talking about guilds, about teams here. We're talking about Ecclesia-sized organizations. Months? Years? This point is debatable, of course, but I believe it still works to base what I'm saying.

Let's now look at something Barlowe says on the game's dialogue:

"Barlowe: You've earned the right to know. Here's all the rest: In ages past, there was a hunter's clan. Their holy whip held Dracula at bay--until, as time marched on, they disappeared. The whip lost, men created other tools... such as the Glyphs Ecclesia controls. Through constant hidden struggle round the world, we proved Ecclesia's mettle to mankind. And so, in secret, certain men of power then placed a certain object in our care."

Past tense again. The dude is not even talking in decades, he's talking in AGES. Remember that the "hunters' clan" existed up until Richter, which is supposed to be not too long ago if Ecclesia takes place during the early 1800s. The use of "ages" is not literal, of course, but still used to mean "a really fucking long time ago, son." Then he says that through constant struggle around the world they proved their worth, which I believe to be something that is not done in one week, too, specially with multiple competing organizations trying to one-up each other. So here's how the timeline goes more or less:
Early 1800s -- Ecclesia is born

???? -- Ecclesia endures while all others fail, proving their worth
???? -- Ecclesia is entrusted with the remains of Dracula
???? -- Barlowe tries destroying them with their glyphs and fails
???? -- Barlowe studies the remains and extracts Dracula's power
???? -- Barlowe creates Dominus

If you still believe Order of Ecclesia takes place during the early 1800s after this, then there's nothing else that can prove to you the contrary. The game says numerous times through implication or directly that the early 1800s are PAST TIMES. The game itself takes place after ALL of this stuff has happened.

And then we get to Shanoa, who's 20 years old, and was taken by Ecclesia at "an early age," as confirmed by her bio on Judgment's manual. SHE WAS TRAINED TO HARNESS DOMINUS which probably means that Dominus was already a thing by the time she became part of Ecclesia, or became a thing while she was little. Suddenly the timeline looks like this:

Early 1800s -- Ecclesia is born
???? -- Ecclesia endures while all others fail, proving their worth
???? -- Ecclesia is entrusted with the remains of Dracula
???? -- Barlowe tries destroying them with their glyphs and fails
???? -- Barlowe studies the remains and extracts Dracula's power
???? -- Barlowe creates Dominus
???? -- Shanoa joins at an early age
???? -- Shanoa is 20, Order of Ecclesia happens

See, research is also not something done in two days. It takes time. And we're talking Dracula here. How long do you think it took Barlowe to test all of his glyphs against the vessel, then study Dracula's magic, then extract it and then forge it into a group of glyphs? And that's assuming Barlowe succeeded on the first try, something that is almost never true.
"B-but IGA said on an interview that the game is set during the early 1800s!"
He said this BEFORE the game came out. Understand this: Things change as development progresses. He could've changed his mind midway development, which is fixed on the game itself with as much work as editing two or three lines of text.
Conclusion: Ecclesia doesn't take place early in the 19th century, and the manual, intro and dialogue supports this. "But IGA said" is not an argument because the manual, intro and dialogue are also words of IGA, effectivelly retconning his own past words.
