In his youth, Professor Snape invented the dark curse, Sectumsempra. What awful thing does this spell do?
Answer It causes a cut on the victim that will never heal
The word 'sectum' translates as 'cut' and 'sempra' as 'forever.' Those affected by this deadly dark curse are left with a life-long cut that will never heal. That is unless you have Professor Snape by your side to perform the song-like incantation of Vulnera Sanentur.
