How long has passed in-game since the avatars first clashed? 

That is, between that point and the current events of the Realta invasion and decimation

[@Kho] For sure it's placed chronologically before Luna's meeting with Ventus, which happens several weeks prior to Logos' invasion.

I'd say, anywhere from a month to a couple of years? (before Logos' invasion)

That. Though i'm leaning towards a year, maybe a year and a few months.
