Apart from training knights from Carona..... there were also several other benefits as well.
For one, Carona citizens could get Visas ranging from 6 - 8 months time.... while regular people could only stay a maximum of 3 months instead.
And if they were the royals of Carona, then of course..... their time frames would be extended as well.
The royals could get 1.5 to 2 years time on their Visas when coming to Baymard.
.
Typically when the visitors came, they were given 'Visa I.Ds'..... that were enclosed in plastic coverings, just like regular I.D cards.
The idea was that once they got into Baymard.... they were expected to go to the 'Baymard PASSPORT' office at District C.
The office would measure their height, write down their eye, body, and hair colors.... as well as take note of any distinctive marks around their faces and so on.
