A mysterious realm that appears suddenly in vast seas expanses and traps cultivators, cultivators believe that this world is actually the stomach of a legendary devil beast, the Rahu or otherwise might be related to the netherworld.
The only powers you’ll be able to use in the umbra realm are a few crude martial arts and umbra energy.
There are about Nine villages scattered throughout the Umbra Realm. Food is scarce here so apart from a few pieces of fertile land, the rest is barren from the heavy umbra Qi. A majority of the umbra beasts possess poisonous flesh, and apart from some special varieties, we are incapable of consuming them. Although demon beasts are able to consume them, humans would perish upon eating them. As such, only useful people are allowed to live in villages. Anybody who is useless will be driven away and have their lives run their natural course.
