Sivean was the first planet to be colonized outside of the Sol System. Named after the Sivean Society, an organization that brought many of Earth's nation together in order to escape global warming.
Sivean is covered in a thick vast jungle filled with nightmarish creatures, plenty of resources, and mysterious to be found. Siveans jungle is covered in massive trees, blocking out the sun. Below these trees lies plants that struggle to survive as they fight each other over sunlight. Within the vast caves of Sivean lays crystals of unimaginable size.
While most of the Planet is covered in a thick jungle, there are rather large oceans that hold many mysterious that have yet to be explored. These oceans also have massive trees in them, and they are covered in fungus and moss.
