Smashed asteroids

[SpomJ]

Spaced In?

So the basic idea is that there's a planetoid with multiple parts, separated by large magma channels. The biome set in each part is different, so that there's industrial interest in going from one part to another.

The difference between this and magma channels trait is that the second is treated like a regular biome, it doesn't separate anything while the first would completely separate one part from another. Depending on biome and geyser set it would pose various challenges to overcome.

So yeah it's basically flipped asteroid, but another one on top of it.
