“Cavendish. Our new world. Our frontier.” Years ago, they’d found a gas giant, Aegir, named after Ran’s husband, the god of the ocean. Aegir was too large for life—akin to Jupiter.

The right temperature for water to be liquid on the surface given the right atmospheric pressure. For life to potentially grow.
