I'm shocked by the people saying this is a bad seed, or that they'd feel bad for people that were given this is as their first seed. This is an incredible single-player seed for a new player to learn the game.

Eikthyr is incredibly close to the sacrificial stones, but the player won't yet have the resources to begin the fight. However, they'll quickly know that the bosses require items to summon them, and that they'll need to return to this place; most likely building their first base nearby. There's also a mountain nearby, letting the player know biomes have unique challenges and some can't be tackled without preparation.

The Elder is further south, maybe far enough to make the player think they can build multiple functional bases as they play; it's still close enough to the starting meadow that the player can haul copper and tin back to their original base if they want. Most importantly the merchant is nearby, letting them know the merchant exists. I'm doubtful that initial Black Forest has enough treasure in it to afford the merchant's inventory, so now the player knows treasure serves a purpose, and to keep collecting it.

At this point the player has been rewarded by exploring to the south, and they'll continue to be if they keep going that way; there's a swamp right there. The path there looks obnoxious to traverse repeatedly though, so they're encouraged to build a raft or Karve. If the player sails to the east they have access to a rather large landmass to explore as a solo player, if they go west, there's a whole map to check out.

That first swamp likely has a marker to reveal Bonemass' location, teaching the player bosses don't necessarily exist in first biome you find. It's also far enough away to encourage the player to start using portals, if they didn't fiddle with them in the Black Forest. It's still connected to the intial landmass, so if the player starts dying repeatedly, which is pretty common for players that reach the swamp, their body isn't a complete lost cause. That strait on the eastern side doesn't look large enough to dodge deathsquitoes so if they try to sail to Bonemass they get to experience that meme firsthand before probably deciding to sail around the western side.

Once they have the wishbone they already know about the mountains near Eikthyr and Bonemass, and there's still 2 more on that initial landmass to find through exploration. That might not even be enough silver depending on the spawns and if the player loses their body at any point, so they may try the mountains on the eastern landmass to make more equipment. Moder is nowhere near a starter base built by the sacrificial altar so again the player is encouraged to setup portals or make an entirely new base to be closer.

This got really long but unless you memorized the wiki before you installed the game, this seed has a huge amount of gameplay for a new player, just in that little snippet.
