Kastelle: The Moon of Armor-Clad Viscus

The surface is a cold fortress. The core is pulsing red, with nerves drawn tight.

The caverns spit out bestial horrors. The lords adopt them as their Herald-bearers.

underneath our armor we are all meat.

the demonyms are fast and loose. I was thinking:

Moon Proper Noun: Kastelle / Kastelle-itself; the Autonomic Heart / AutonomicHeart-itself

Moon Adjective Form (generic/geographical): Kastellen ("Kastellen rock")

Moonfolk noun-adjectives (social demonym, for people):
Kastellet (singular unit only; gender neutral: (n.) "The Kastellet met with the Heraldic Chimera"; (adj.) "The Kastellet trader smelled the rose").
Kastellene(s) (plural units only; gender neutral): (n.) inclusive of all the people of Kastelle. "The Kastellene people"; (n.)  indicative of more than one Kastellet "The Kastallene nobles retreated to their chambers"; (adj.) of having origins in Kastellene society "The blacksmith studied the Kastallene armor".

Kastellengard - sounds cool. i think these are some bad dudes. crucible knights. open to interpretation as to what they do.
