There were three of them.
Harry James Potter. Ronald Bilius Weasley. Hermione Jean Granger.
Together, they made up the Golden Trio. The children who rid the world of Lord Voldemort. The Wizarding world hailed them as heroes, and smothered them with adulation. Together, they performed things that a fully trained squad of Hit Wizards would have hard pressed to do.
How?
Each of them brought something to the mix, and took something along with them.
Harry taught Ron that money and fame weren't everything, and that friends and family were more important than anything else.
He showed Hermione that being a know-it-all and muggleborn did not, in any way, affect most people's opinions of her.
Ron showed Harry that he wasn't "abnormal", and that people would actually like the 'scrawny boy from under the cupboard' a lot.
He taught Hermione that however bossy and ugly she may be, there were people who would stick with her through the bad times.
Hermione showed Harry that he had much more courage that he gave himself credit for, and that courage was better than brains at times.
She taught Ron that however much he thought his brothers were better than him, some people saw him for what he was and appreciated him for it.
They met on a sunny day on the Hogwarts Express, and while Harry and Ron hit it off immediately, it took a mountain troll to bring Hermione into their little group. From then on, they were inseparable.
Together, they stopped Quirrell's bid for the Sorcerer's Stone.
Harry and Ron, with a little help from Hermione, rescued Ginny from the Chamber of Secrets.
Harry and Hermione rescued Sirius Black from an unfair fate.
Ron and Hermione supported Harry after he saw Voldemort return, and throughout the ridicule that followed.
They followed Harry into the Department of Mysteries.
They defended Hogwarts in their sixth year, while Harry was away with Dumbledore.
Together, they hunted for Horcruxes, mostly united, and then finally, killed Voldemort.
But they hated the fame. They wanted normal lives, and they got as normal as they could married Hermione, and had two children. Harry married Ginny, and had three.
They soon grew old, bent and shuffling. They died, the last of a golden age. Their memory, however, lived on.
The three kids, innocent, unburdened by troubles, happy and gay, who met on the Hogwarts Express, lived on in people's minds and hearts.
For they were heroes. They were the Golden Trio.
