Arden was the homeworld of the Shenn. It was a planet of hills and forests. It had more than one continent.
In 2670, humans established the stage one colony on Arden. They constructed many bases. Among them were Touchstone Base, located on the northern continent, and Oberon Survey Camp, near the Phebe mountain range. (PROSE: Shadowmind)
Geology
Hypergems were found in great quantities on Arden, though the colonists named the gem oberonite (due to the proximity of where they were found). (PROSE: Shadowmind)
