A planet full with vibrant forests of Oalyan trees, a type of tree that produces oxygen even if there is no Co2.

Yomead had no atmosphere until the non-native Oalyan trees have appeared. Which only grow on the best of soil, that Yomead has, most know for the fact that if mixed with gravitite via smelting, creates a strong metal known as Hirua. Hirua emits a highly toxic gas, but the metal is one of the strongest types of metal, but the least Durable metal aswell.

Back on topic, the Oalyan trees created a large oxygen filled atmosphere able to sustain life, such as humans.

It has a nice moon called Fornade.
