It's easy to understand once your more prone to learning it. Which is why I'm making my book on it

Damnn,the lore goes crazy I guess

The powers they have are really something different besides all of that. Plus he didn't make the months change. The HUNTERS did. They have godly abilities considering they had to kill Jesus, God, And all other gods. But no THE DARK LORD and his father's hold the ability of DOOM. DOOM in the definition everyone knows in my universe means: The Fall of All to be Seen.

So are the powers only destruction based or is it more something to do with reality bending or some sh*t because y'know, he destroyed reality and messed up how the sun moves making 20 months in a year instead

Ummmmm let's just say thinking about dominating something he could destroy what it was or do what it was.
