I posted this over on G+, but I also want to post it here for quick reference:
I can't remember where I saw it, but someone posted a hexmap of a dead island which sort of looked like something from the original 8-bit Legend of Zelda.
Last night I tried looking for it but couldn't find it. So I made my own. The hexes are 92 x 86 in Hexographer -- I wanted 1-mile hexes so this looks right to me.
Hex 02.08 is a VERY deep lagoon behind a coral reef.
Hex 06.07 contains ruins; the sea is encroaching and has turned the earth to bog.
Hex 08.02 contains some kind of monolith looking out over the sea.
The rest you can figure out on your own.
Feel free to fill the hexes in the comments, even expanding what I commented on above.
Maybe this can be something for #GorgonQuarterly eh ?
