It looks amazing! I'm very impressed that you managed to name so many of the islands! And the map prompts so many questions!

Is there any water? You mention that "The sky is covered in birds, the ground in birds, and the waters in fish with wings" ..., but I couldn't work out where the fish are, is that because of the scale, have we zoomed out too far to be able to see lakes and rivers? Do islands collide, or do their gemin cores prevent them from crashing? Do islands grow, are larger islands older or are they formed from more powerful gemins?
