Great!
Ok, hear is what happened...behind the curtains of The War of the Loins. We know that the Lucavi each represent the 13 Zodiac, but we only 7 in the game. What happened to the other 6? Were they still stuck in The Rift, like one of them said? Well I have come to a conclusion that Exodus and Famfrit did indeed come through, but like all of the others, they were destroyed.
Let's start with Famfrit, Aquarius. He is never seen in the game, yet Beowulf somehow got his hands on the Aquarius Zodiac Stone! How did he do that? All we know are the words he said when handing it over, “Let us just say I have my own debts to settle. As have you." We know that Beowulf is a former Knight Templar and the Lucavi had pretty much taken over the them, but Beowulf was away trying to find Reis who had been transformed into the Holy Dragon by Celebrant Bremondt Freitberg.
Now we know that it had been years in the search for the Holy Dragon and I have come to the conclusion that during those travels, Beowulf came across the plot of the Lucavi in the Knight Templar and returned take see if he could stop them before returning to his search. This in turn must have brought around the fight with Famfrit and whoever he had chosen to be his host. Beowulf defeats Famfrit, takes the stone and leaves.
So that's what happened! Beowulf fought against the Lucavi and took Aquarius. What do you think?
Famfrit is quite the Esper and his fight with Cid in FFXII was just epic.
To say who would be his host would is something beyond my reach, as I do not know who the host would be. I guess an OC will have to take the spot. And let's have it be a girl!
Now, would you like to hear the rest? The other possible theories for Libra and maybe others?
