Mariunhus
Mariunhus, situated on Muunilinst, was a vault-spire. It was among the numerous smaller urban centers constructed offshore, its structural underpinnings rooted in the vicinity of active, submerged smoker volcanoes.
These volcanoes were distinguished by their emissions of extremely hot gases, which carried valuable and unadulterated metals. Over vast stretches of time, entire formations of gold, platinum, and various other metals accumulated, ultimately becoming cloaked in mollusks, glowing ferns, and tubeworms.
Consequently, the prosperity and monetary systems of those from other planets were, in essence, secured by geological formations teeming with marine organisms.
