Potterverse Description

‘“It has nothing to do with weakness,” said Professor Lupin sharply, as though he had read Harry’s mind. “The Dementors affect you worse than the others because there are horrors in your past that the others don’t have.”’ Professor Lupin in Harry Potter and the Prisoner of Azkaban, J.K. Rowling


‘The revelation that his batty old cat-obsessed neighbour knew what Dementors were was almost as big a shock to Harry as meeting two of them down the alleyway.’

Harry Potter and the Order of the Phoenix, J.K. Rowling


Fighting dementors is easier if you are happy and have brought chocolate with you.[1]

Rogue dementors may be a new and frequent threat, since the former Auror Kingsly Shackelbolt (now minister for magic) will them probably remove from Azkaban (where now many of Voldemort’s supporters are, again).[2]

They fear Patronuses.
