Twilight beginning dark magic on door S3E2

Since season three,dark magic has become a recurring danger in FIM

Hello there. For the most part,Equestria tends to be a bright,cheerful, and happy place. While the odd dialema occurs,most would consider Equestria a paradise. Season three however has intruduced us to something far more sinister lurking within the cracks,and that would be dark magic. This blog is going to just be me taking notes on every time that dark magic (Or Sombra's spell,as some call it) is used throughout the show. If I miss anything,please let me know in the comments. 

(Work in progress. Come back soon!)
