Chetzia III is planet in Romulan space close to the Romulan Neutral Zone. The planet has at least two military bases and in 2377 became a base of operations for the Wardens. When the Romulans first arrived on Chetzia they were exposed to a deadly virus and in response they genetically modified a species of plant to kill off the virus. The virus was successfully destroyed, however the genetically modified plant has now begun to take over the planet. In addition to the extensive jungle, Chetzia is also home to number of insect and bird species.
