The Fountain of Magical Brethren was a fountain that stood in the atrium of the Ministry of Magic. Within the fountain, gold statues portrayed a wizard, a witch, a goblin, a centaur, and a house-elf. The wizard and witch were modelled after Camulus and Trinity Blackwell, the goblin after Azgul, the centaur after Harmonthrep, and the house-elf after Jodo.
The Fountain had the powers of the "fountain of youth", and it's waters reversed the effects of age. It was made when the ministry of magic was founded, and it existed until Harry Potter cast the spell of destruction on the Ministry of Magic using the 7 treasures of the founders, and overthrew the ministry. Harry Potter recovered the statues, and moved them to his royal castle for his own courtyard, but the powers of the fountain were bound with the Ring Of Power, granting Harry Potter immortality and extending his reign indefinitely.
