Gaea is a temperate world with a moderate climate. It is covered in lush vegetation, including a variety of plants and fungi. The plants are the dominant lifeform on Gaea, and the fungi form symbiotic associations with the roots of the countless plant species. There are no other lifeforms on the planet besides plants and fungi. The fungi provide an essential service to the plants, breaking down complex molecules and releasing nutrients that the plants can absorb. In return, the plants provide the fungi with shelter and a source of food. The relationship between plants and fungi is essential to the health of the ecosystem on Gaea.
