@Zhenja:
Yes very possible, but the post I qouted was "maybe its kaido and BM captain on their younger days, just like buggy and shanks with roger".
So it's not possible that Big Mom had a captain, like Buggy and Shanks.
Yeah, but maybe this alliance had some kind of leader. For me it is hard to imagine that Kaidou and/or BM give the lead to anyone though.
But I like the thought, that there was some kind of badass Anti-Roger-crew long ago. Just like the SHs have the BBs now.
But I start to think that just like DR, Goa could be another country that once was home of one of the 20(well, 19 without Nefertari) founder kings.
Why should a CD visit a remote country in East Blue? It's a long journey. And risky if they go through calm belt (unless they have a passage from RL to each of the Blues).
Another reason is the country's architecture.
Notice how DR's castle was built on a huge rock lookin down on the people. Goa's country looks QUITE the same.
Walls divide the people from different classes. Maybe those original 19 kings haven't been as pure as they are portrayed here.
Usually Sarie's dad should be at the Reverie right now, but thanks to Stelly, Stelly now has to make his pledge, since it is his first Reverie. Would explain why he was the only monarch in the throne room (atm).
I wonder if the Nefertari's weapon is among the 20 kings' weapons. I counted just 19 in that total panel with the throne.
Maybe it is among the other weapons on the lower level. EDIT: Nevermind, the Gorousei-lookalike said "20 weapons around the throne".
If 50 countries are at Reverie, it means 19 countries like DR (who once were ruled by the founder kings), Arabaster and 30 other Countries who joined the WG afterwards.
