If Dust is analogous to a weird blend of Westeros and Essos, and Ash is basically all Essos, but a little underdeveloped compared to actual Essos. Then Isla Diablo is probably analogous to Sothyros.

Which means it's got dinosaurs and manticores but no one ever actually goes there and it's just horrible. I feel like we should retcon some names though-- Ash might be a more appropriate name for Isla Diablo than Ash. I wanna give Binary Star a more apropos name anyway.
