The custom map was created by one of our admins using worldpainter, he did it for free. He has been using it for years and is very experienced, so he did a great job. We are now looking for buildersr to build it up, with cities, towns, ports etc.
Please post here or pm me if you are interested in becoming a builder, this is a very promising server idea and it could be very popular with the communitys help.
Also post suggestions or opinions you have on this, we are open to criticism
