Okay, guys - here's the world. On it, I've marked six locales that seem interesting, each in its own way.

<!> marks a locale, as suggested by puutuulion. It's a very flat, frozen tundra. Wilderness/Untamed wilds, with very deep soil and clay.
<2> Is wilderness. Forested, with very deep soil, a stream, and clay.
<3> Is a haunted forest. Much fun to be had. Clay, deep soil, and a brook.
<4> Is a calm area. Little soil and a stream.
<5> Is mostly wilderness mountain, with one tile of woodland. Little soil, NO SHALLOW METAL, and a volcano.
<6> Is a calm, temperate zone. Deep soil, clay, and a major river.
Other than embark <5>, all are pretty much flat. All candidate locales have access to at least one shallow metal, one deep metal, and flux. Except for <5>, which has no shallow metals.
Poll to follow.
