Professor Trelawney, who taught Divination, was a mad witch who wore glasses as thick as the bottoms of glass bottles. At least, that was how most young wizards saw her.
She was nervous and jumpy every day, often saying things that made no sense. She wandered around the castle in a perpetual daze, and whenever she encountered a student or professor, she would spout some kind of nonsense she called a prophecy.
According to her, every year some young wizard was going to meet a terrible end.
She said it so often, and none of it ever seemed to come true, so no one believed her.
In fact, there were many people like her in the Wizarding World. They relied on talent rather than learning, and in fields where the results couldn't be easily seen with the naked eye, unlike Charms, masters and frauds were all mixed together.
Anton certainly didn't think Professor Trelawney was a fraud.
On the contrary, he had tremendous respect for people with innate gifts like hers.
Grindelwald had once told him that there were countless ways to manipulate Fate. Using people's hearts to influence events was simply the clumsiest method; the most formidable practitioners were the Seers.
Their prophecies interfered with Fate. When they lacked the strength, luck, and wisdom to resist, Fate would follow the path laid out by their prophecies.
Prophecy was sometimes like unconsciously casting a spell on the entire world from a certain dimension.
The future couldn't be seen because it was full of uncertainty. A future fixed by prophecy was like laying down tracks for what was to come. Not every wizard had the ability to go off the rails.
So the magical fields that opposed Prophecy were actually Curses and Blessings.
