Styca Realm
Out of the 4 Human Realms, the Styca Realm has the most number of trees. There were areas where people can see trees as far as the eyes can see
Of course, there were still cities that have modern infrastructure. But overall, the Styca Realm has a lot of trees in them and it has a unique architectural look that combines both nature and technologies
Since there were fewer massive buildings in this realm, the Styca Realm has a lot more houses for the common people than the other realms
Because of that, out of the 4 Human Realms, the Styca Realm has the largest population
They have at least 50 to 70 percent more people compared to the other three realms
For such a reason, this realm was also the one that Keon and Craige decided to destroy
After the initial unwillingness, when Keon already set himself in killing trillions of people, he only thinks things in a logical way
