Chloris

Chloris was a verdant planet, covered in thick, foggy forests. A species of native, mobile plants called Wolfweeds were found on the planet, along with a group of primitive humanoids. These humanoids were ruled by courts, still used astrologers and fought with simple swords and daggers. Despite this, they did have an idea of space travel, though they couldn't go into space themselves.

The humanoids of Chloris were kept at a primitive level due to the scarcity of metals on the planet. This stopped any mass production of materials and also stopped any clear cutting of the forests. Eventually, Chloris was discovered by the Tythonians of Tythonus, who set up a trade agreement. (DW: The Creature from the Pit)
