About this build
A topological impossibility made real through Magrathean engineering. The interior resembles an exterior; the exterior resembles an interior. Navigation requires philosophical training.

Customer reviews
We can conduct our research here. The ecosystem is stable enough. Not ideal, but functional.
Highly satisfied.
Magrathea's attention to detail is unmatched. My bespoke moon system includes dormant but realistic volcanoes and gravity wells that create spectacular tidal phenomena. Science and art perfectly blended.
The hollow planet's interior collapsed. I almost died exploring the caverns when sections failed without warning. Magrathea accepted no responsibility.
Cannot recommend Magrathea highly enough. My polar ice caps world maintains perfect temperature stability. The geological surveys provided were incredibly thorough and accurate.
