This is basically the reason I had Emilia share a city with Gareth, at least. Most of the protagonists in older RotMG lived near each other, most of these guys live on the other side of the globe from each other.
Err, not really Elf. If you were in the same situation, and you then made landfall on earth immediately afterwards. You would have absolutely no reason to stick around. It's out of character for any sane person to stick around after that. Most would want to go home after the traumatizing experience of being kidnapped by lizardpeople. Most would want to go home immediately.
If you're taking issue with the plot, that would be Sanure's area as I had no input in this plot whatsoever. If you're taking issue with how people are being kept together, well, I maintain my response.
Also, Akroma raises a good point.
