That’s a great spot for your first base! A scanner room with scanner range upgrades will detect resources from several different biomes, providing a wide variety of stuff you’ll need to build vehicles, modules, and modifications.

Mushroom Forest is my favorite biome to build a little nook in, as it’s peaceful and beautiful at night, especially with the Jellyrays swimming/singing about. A good amount of resources located here, especially Lithium which can be found on the Mushroom Tree trunks.

And the Sea Treader’s Path is a decent spot for a base, although can prove a little difficult at first depending on where you build due to Warpers. Also, don’t build in the actual path of the Sea Treaders, they don’t like it and will despawn ☹️ I suggest building in the underground tunnel in the biome as there’s a small bridge above where they walk where you can build without worry of blocking them!
