Statue curse

The statue curse, a curse that will, once unleashed, turn individuals into statues. The texture of the statues is the same as the Merperson Trident discovered in the Portrait Vault.

History
In the 1989–1990 school year, a male student was turned into a statue in the Clock Tower Courtyard as the result of this powerful and malign curse being somehow unleashed. Beatrice Haywood first discovered the student, before the situation being investigated by Severus Snape and Jacob's sibling.
