Dusk

I'll finish it later. Dusk is a unicorn pony, docile and typically lacking in confidence, with a fascination for military history. This is reflected in her cutie mark, a sabre lying across a book.

Early life
Dusk was born to a Ponisian family, who emigrated over to Equestria when she was a few months old. Although they loved her, the traditional Ponisian values they rigidly stuck to, caused them to become distant.

She attended various local schools throughout her school years, meeting Twig and Buttermilk; likely the only two ponies she can truly call friends.

Sadism
Dusk is amused by, and takes pleasure in, the psychological and physical suffering of other ponies.
