I forgot to mention another parallel between "The Creation of Ea" (the Earthsea Creation Story) and "Malakas at Maganda" (a Filipino Creation story). While the Immanent Grove figures prominently in the Earthsea Cycle, the grove of bamboo serves as the birthplace of humanity in "Malakas at Maganda."

Anyway, I decided to search Google for Manaul, one of the names given to the bird who flies between sea and sky, in search of place to alight.

• Philippine Creation Myths by Penelope V. Flores, Ph.D.
• Mythology and Folk Lore: A Creation Story
• "Manaul" is a name for the Philippine Eagle, also known as the Monkey-eating Eagle.
• Hiligaynon Mythology, although, for some reason, this reminds me too much of the Greek Myths.
• A brief mention of Maguayen, goddess of the Sea
• Stories that mention Manaul, Kaptan, and Magwayen. The bird and the war of sea and sky is attributed to the Indonesians, once again making clear the relationship binding all Austronesians. Interestingly, the grove of bamboo is on the island of Panay, one of the Visayan Islands. Since I'm not a native speaker, I can't say this with confidence, but I'm pretty sure that in one Austronesian language at least, panay means something like "completely," or "entirely." (Hmmm. So is Panay the equivalent to Roke, then?)
