If you really want to link the games together, just do what I did; My character from FF11 was using Atomos until one day something went wrong and I got barfed up in Eorzea (Atomos was showing up just before Dalamud fell). That's the basic backstory to my character in FF14. Done and done, right?

Although, I still play FF11 on occasion so I like to pretend it happens in the "future", heh.
It honestly makes sense, and could be the reason behind the whole Dissidia thing aside from Cosmos and Chaos summoning them. Atomos could just be the method to cross dimension travel.
