The Harry Potter series has expanded far beyond what was shown in the books. Voldemort isn't the only evil figure in the Wizarding World, with the history of dark witches and wizards stretching back thousands of years. In fact, far-reaching places like Azkaban and America's Ilvermorny School also have ties to those who practiced dark magic, and there's a lot of things that fans don't know about. There are also further points of interest about established villains that give them another layer of meaning. Voldemort is just the tip of the iceberg of the presence of evil in the Wizarding World.
Barty Crouch Jr. Was Among The Most Accomplished Students In Hogwarts HistoryPhoto: Harry Potter and the Goblet of Fire / Warner Bros. Pictures
In his hopes of gaining his father's attention, Barty Crouch Jr. became a highly accomplished student at Hogwarts, to the point where he achieved as many as 12 O.W.L pass grades with an "Outstanding" grade in every exam. In comparison, Hermione Granger only completed 11 O.W.L. papers and received an "Exceeds Expectations" in grade in one of them, placing Crouch far ahead of her.
Moreover, Crouch also received the highest grades at N.E.W.T. level, making him amongst the most accomplished students in Hogwarts history. Of course, this meant nothing to Crouch, who still failed to achieve his father's approval, motivating him to join Voldemort after seeing the Dark Lord as a replacement father figure, and his legacy is to be the Death Eater who brought Voldemort back to start the Second Wizarding War.Diabolical detail?
Azkaban Was Originally The Lair Of A Dark WizardPhoto: Harry Potter and the Prisoner of Azkaban / Warner Bros. Pictures
Ekrizdis was a dark wizard who found a secluded island in the North Sea. His main prejudice was against Muggles, so he used this island as his secret lair where he lured unsuspecting Muggle sailors and proceeded to torture them to their demise. Ekrizdis had such powerful enchantments on this fortress that it was unplottable even by wizards. By the time Ekrizdis died, he had tormented countless Muggles, so much so that Dementors became attracted to the location.
When Ministry officials finally saw the fortress due to the concealment charms being removed from Ekrizdis' demise, there were hundreds of Dementors who refused to leave. It was after two centuries that this lair became Azkaban prison, with the horrors Ekrizdis committed running so deep in its walls that Dementors continued to be attached to Azkaban.Diabolical detail?
Antonin Dolohov Created A Non-Verbal Dark Spell Only He KnewPhoto: Harry Potter and the Order of the Phoenix / Warner Bros. Pictures
Antonin Dolohov was a particularly gifted wizard in the matter of the dark arts, as his evil nature empowered him to create his own spells. He was so adept at this that Dolohov came up with a curse that only he knew how to cast. For this reason, the curse's name isn't known, as Dolohov cast it non-verbally with a slashing motion.
It was this spell that Hermione Granger was caught with in the Department of Mysteries, as evidence by the zigzag pattern of the spell's purple light that gave Hermione severe internal injuries and it took weeks to cure her since it was unknown what medicine would fix this.Diabolical detail?

According to JK Rowling, Grindelwald is lying as far as his manipulations are concerned, but he was indeed a Seer.
This means he was gifted with the Inner Eye from birth and had genuine visions of the future.Diabolical detail?
