is a very nice post mislands update seed. It has a large center island with all biomes except mistlands and ashlands. Several crypts in the swamps contain enough iron scrap for 2 players and the mountains contain enough silver deposits to outfit 2 players.

Haldor is on an adjacent island. The first and 3rd bosses are on the start island. The 2nd boss is an unfortunate distance away but the 4th boss is on an adjacent island. I haven't found Yagluth or the queen yet.

There is a very nice large flat spot for a huge base in the meadows that isn't too distant from the north or the south shore of the island to transport ore by ship and the boar stones are farther than 500 meters from the start location so you can find 2 star boars and still walk them back to your main base.

If you want a truly hideous seed as a challenge to start up use:

The central island is all divided into pieces by rivers and steep valleys even the meadows. Every thing is a steep climb or a steep drop. 1 tiny mountain near the center. Copper and tin are all very far from the start point as are the dungeons that contains skeletons and your first few surtling cores. Only the first boss is near the start location and there is a small peninsula in the central sea that is just barely flat enough to support a small main base though access to it by water is excellent.

All the boar stones that are far enough from the start location to generate starred boars require swimming or sailing to reach and return. A true night mare from stone age all the way to silver. (Yeah, this is the seed I'm currently playing).
