Oko A is a vibrant planet covered mostly by ocean. Under the surface, expansive reefs are home to abundant sea-life, making this planet a key spot in the system for underwater nature-watching. Earthquake activity on the ocean floor has molded stunning underwater mountain ranges and deep valleys, making exploration below the surface a breath-taking experience.

The only landmasses on the planet are a large flora-covered continent and a much smaller landmass near one of the poles. The former is home to a great forest, filled with numerous creatures, and rolling hills of grass that are equally vibrant with life. The latter is a rocky ridge of an island, raised from the ocean floor by millennia of tectonic activity. The temperatures remain steady throughout the planetary year, making Oko A very habitable for settlers. The fairly flat terrain found on the main landmass is ideal for hunting and farming, as well as the construction of personal and commercial facilities.
