Muspilli

The Muspilli are a species native to the planet Hazar. They are unique among all known lifeforms in that they do not require water to survive; rather, they survive by consuming magma, ash, and other igneous rocks. They are able to survive only in incredibly hot environments, above 1000 Celsius. No Muspilli have ever left the planet Hazar.

Society
The Muspilli have a small-scale society on their planet. They live in small tribes on igneous rock islands in the vast lava oceans of Hazar. They often dive into the lava for minerals to consume, and to collect rocks to build with. They also use fire coral for various things, such as decoration and for building boats.
