The hand in the screen

Atta Hamlet is a fangirl. A major.

How major?

When there's a Homestuck update, she shouts at the top of her lungs "UPDATE!!!!!!!!1!1!1!!/!/"

Atta is a rich girl, and she lives with her Uncle Matt. Sadly, her uncle passed away a little over two years ago, so she lives alone in a large mansion, meant to fit over 20 people.

One day, while reading her favorite internet comic, a static appears on her computer screen, along with an ungodly screeching sound.

Suddenly, the screen when black, except for a blue scratch across her screen. Out of that scratch came one grey hand. A grey hand with sharp yellow nails.
