Life is very long.

Princess Twilight Sparkle had reached the ultimate goal that had eluded alchemists and rulers for lifetimes. Her alicorn prowess granted her a heaping surplus of years to live, and she planned to make each one count to further raise Equestria to greater heights. Even as the landmarks of her previous life melted away to time, Twilight was stalwart in protecting her homeland from anything that dared to disrupt its harmony and friendship. 

Unfortunately, new crises appeared as rapidly as she resolved them. Many of them proved to be far too much for her to overcome, dragging Equestria to ruin. Through the wars and disasters, Twilight always managed to find a way to escape life's judgement. Now she roamed the corpse of her fallen kingdom wondering what actions she could have made at the correct moments that would have saved Equestria from such a horrific fate. 

This would not be the first time that she trotted upon the remains of her kingdom.
