Curses aren't my best area of knowledge; I was never that great at magic. Or at least, even when I had it I didn't delve? Anyhow, most of the curses I'm familiar with are a result of tampering with a protected item, or of getting blasted in the face by a basilisk. With Vallo, anything is possible. Vallo itself may be a curse. Or a blessing, or a punishment, depending upon the day.
