Ahem, no, that's not right. In fact, that is the Mythic Archipelago with the region numbering. I'll explain what those mean later.
First, a note on size and scale:
The Archipelago is big. Take a look at that second map and locate number 57. It's southwest of the reserved island (more on them later too) labelled A (upper left).
See it? Good. That island is the size of Greece. Remember how much history Greece has? How many epic wars and stories, how much mythology? Throw in just the nearest islands and the ocean in between them, and you have an area around half the size of the entire Mediterranean sea, around which practically all the history of the Western World, from ancient times to about the year 1200, is told.
That is just a small piece of the Archipelago.
Furthermore, the islands you see on the map are just the big, major islands. Every writer has the option to create small, minor, and largely uninhabited islands (of which the typical archipelago has hundreds) to set their stories or parts of their stories on, if they so desire.
Reserved Islands:
These islands are reserved and cannot be chosen to develop. Their development will happen either as a group or as the object of special contests.
Normal Islands:
(Apologies for the slight blur - Mythic Scribes Gallery has a filesize limit)
If you are new to the Archipelago and want to join in, select one of the above islands and then reference the lists below to see if anybody has claimed it. If not, then give your island a name and start a thread in the Islands subforum for official development. At the same time, send me a PM telling me which island you picked and the name, and I will add it to the list.
