Because it makes it much easier to establish a new base in Mistlands, or the upcoming Ashlands or Deep North biomes. Copper is one of the most used elements in the real world and in most fantasy settings, so it also makes sense that dvergr would use it in their construction.

But yeah, this isn't the final biome, or even second or third to final...

Considering how slow development is, this probably is the final biome.
