Cassey is a girl cat from another world, when he was 4 years old she was killed by a wolf, his family was very sad and desperate, was both despair that eventually was revived by a "satanic ritual", she revived, but was different, it became a kind of horrible monster, killed his family, then by a staff (involuntarily) invoked demons of hell, destroyed her world, but for some strange reason was teleported to another world, full of "human" was found by Dash & Fluttershy (they were 9 years old), and remained there for eight years.
When I was 12 years old he met the other girls, but something was wrong, she felt strange, started killing people for their hunger,and transformed into something more terrible, in the same way that inadvertently destroyed his world, so did with "Equestria"...

And that's another story.

Cassey was not the scary monster that is now...
