The Legend of Sol, Titan, and Morgan: The Bloody Meadow

They were not prepared for what they saw.
Sol had expected to see something terrible. But she had not expected to see anything as terrible as this. There was no more farmland: the land had been scarred by poisonous mire, turned so toxic that she shivered at just the sight of it. Her siblings felt the same, although Titan was the worst affected by this poison: he quaked with disgust at it, and felt nature's true pain and fury... and a mutant, awful, insidious life in that toxin. Something that stank of corruption, pure and simple.
There were no more farmers here, no ponies left alive: they had all been taken by these things, whatever they had been. Darkness had stained the land from mountain to meadow, and winter itself had been driven back by this stinking mutant heat that now permeated the world.
Their enemy was greater and far more dangerous than Sol had anticipated. Their enemy was... something terrible, far more vile and evil than Sol had thought. And powerful, too, if this was but a sample of what it was capable of doing. The thought twisted Sol's heart... but filled her very soul with fury, too. And perhaps as well, a sense of battlelust. A desire to face such a powerful and dangerous foe, and test herself against it, to see who would triumph: to understand for once and for all, if honor and virtue was really worth pursuing, if it could overcome the alluring strength of raw, selfish power. Of power that was without restraint and without law, and without regard for others... of power, free of the tethers of friend or family or loyalty.
That was what they were faced with: something that destroyed, it that came from a place beyond, with no purpose in mind but hatred and destruction. And Sol was ready and willing to pit her family against this, no matter what this force was, no matter what the cost would be, in order to test both herself, and to understand what the bonds of friendship and companionship truly meant.
She would see if the words, spoken to her long ago, were true or not: she would test for herself now, if by working together, ponies could truly overcome any obstacle and foe in their path... or if that, like so many things in life, was nothing but an illusion based in stupid fantasies, and weaknesses like hope and compassion.
