Yeah but it seems highly likely that was a genuine behind-the-scenes name change, given that it's the same team who made the Agni's Philosophy demo, and given that the "Athia" woman looks incredibly similar (and the name is very similar).
I'd totally buy that they were calling it Agni's Anthology behind the scenes, but then just came up with a new name for the public reveal (probably because they realised most people wouldn't even remember the Agni's Philosophy demo, so it wouldn't count for anything)
