There were roughly 192 registered guilds in Eastern Federation, and even more mercenary groups--some registered, but more were unknown.
Not every guild and group was invited to the annual gathering. But what that meant was that not everyone could come inside the conference room. The association building itself was free to be visited by anyone, so even those who weren't invited could come.
For these people, and those who come with the invited groups but had no quota to sit inside, a screen was available outside the conference hall for them to spectate.
Those who got invited were given two seats each inside the conference room. Unless you were a sponsor, then the quota was doubled. Trinity, or rather, Mortix, was one of those, so Zein could come inside. Rina was already there, waving cutely at them to come and be quick about it.
