Ancient shells pulsing with dull light
Slow, patient, ancient creatures with shells that pulse with dull light. They stand tall as oxen but broader, their backs wide and flat. Their dark hide cracks in patterns like cooled lava, with veins of orange light pulsing beneath — warm, not burning.
The children of the Aries ride them. They carry their young riders with weary wisdom, plodding through the ash fields with the patience of creatures that have seen more seasons than anyone can count.
Fireshells are believed to be among the oldest creatures on Arietis. They do not flee from eruptions. They simply endure, tucking their heads beneath their shells and waiting for the world to calm itself.
