These entities cannot truly step out of subspace, but their mere will, whispers, or a single thought can cause countless changes in the present world.
Some entities can drive an entire race mad with a single thought, and an emotional outburst from some can plunge a weak civilization into war.
After the gods left, subspace became an unknowable forbidden territory, a place that only those beyond Daoist Master and Supreme barely qualify to "see."
When the Human Race first opened the Star River, they were merely a low-level civilization, lacking means to elevate life levels. A large part of their progress to the current position is due to a Martial God who once entered subspace and forcefully destroyed an Evil God attempting to distort the Human Race's faith.
The entire heavens were astounded at that moment, such that even in the years following the absence of the Martial God, no one dared to act recklessly, giving the Human Race a chance to grow.
