We won..... but we didn't?

Ok, so I chose God-King Darius at the beginning, and it says that we won. From what I have read about the event, we have to complete one more mission to get an icon and some BE or something. That's what the site says, the official page! But I don't see ANY missions.... Could it be that only ONE person gets it? That's how I saw it at first till I read some sites..... what's going on?
