Ríộk ná’Áè (/ri-ɔk/ /nə-ə-ɛ/)

The Plane of Solids

"The Plane of Solids", or Ríộk ná’Áè, used to be known as "The Plane of Earth" traditionally. Like it's gaseous and liquid siblings however, it was renamed to match the actual contents of the plane since it's home not just to dirt and rock but also ice, metal, and many more solidified substances.
Originally the plane was barren since all sources of life within had to be created or imported by outsiders, including all breathable air and drinkable water, but as one might imagine and endless source of material wealth is never left alone and any civilization who has the ability to enter the plane quickly sets up a mining outpost within.
