Here, in darkness of my prison, unmoving, I have laid here for hundreds of years. A god does not need food, water, air or sunlight. Eternity can be unbearable if you have nothing to keep you occupied. And what can you do, if you are locked in dark, cramped chamber, surrounded by all types of magical barriers?
You start looking for a gap.
I still remember my sweet, beautiful Nightmare Moon, so bright and so proud. She would smash these locks, break the barriers apart. Leave nothing but slightest embers of magic, which would melt into her magnificent black mane. And then, she would make night and shadow itself kneel before its true goddess. B
