I'm not sure if the area on the test server is how the final Lobby area will end up appearing as, but with the current map there is a tiny visual glitch. Currently, the rest of the island is blocked off on each side by rocks and trees. If you attempt to walk into these barricades, they will glitch and turn invisible. The zone also has no name, showing up as ??? in the search results and as Riverne #B01 in the login screen.

It all has a very temporary feel to it, so I get the impression the final area may be something else entirely. If that's the case then feel free to disregard these nitpicks with the temporary lobby area.
