The old Linden Home continents down south on the grid should be moved next the Bellisseria continent (just south of it). There is a massive blue void area.
There could be big opportunities here including adding new connections such as bridges, underground tunnels, roadways etc, railways to connect the two.
The old Linden Home continents sandbox regions and those areas that are more active could be merged into it all.
This is a massive challenge but I'm sure it can be done. The big move may be a better way to preserve the old Linden Home continents than shutting them all down.
