What is hallowflow? Is it similar to some sort of magical energy?

I think it is some type of magical energy but I assumed it was something like Divine Energy or something since the amount of Hallowflow a nation has depends on how much the people of said nation worships the God of the planet I think..idk but also it seems more like the Sun to me hopefully we’ll get to know more about it through BWAT’s posts or from the second season.
