The Rule of Twivine Sparkle

Twivine laughed. Her reptilian eyes scanned the scene. Her open mouth was bared in a cruel smile. Magic trailed into her mouth and ponies froze as their magic drained into her mouth. Smiling in delight, she flew back to The Tree of Disharmony and fed the magic to the tree. The tree absorbed the magic and changed it to dark magic. The tree became a bit more stooped and frail.

"Soon all of Equestria will bow towards me!" She laughed sadistically. She opened her mouth and the tree's magic flew into her mouth. She grew in size, her fangs growing longer and sharper.
