A long, long time ago...
Godric Gryffindor stared into the misty countryside. Rain poured onto the moors, the wet, dripping landscape around the abandoned castle. Some time in the future, that old musty castle would become the Hogwarts Wizarding School but for now, nothing was special about it.
"Godric! I've found someone here!" shouted Salazar Slytherin.
Those two were best friends, and always had been. they had known each other since birth. Godric tailed after Salazar into a dark room. It smelt terrible and the only way in or out was through the large hole in the wall. Then he heard sobbing, or was it laughing? A young lady of twenty was there reading a book on extremely advanced spells. She saw them and smiled. This was Rowena Ravenclaw, an educated girl, and clever beyond years. Another lady came out behind ripped curtains.
"Helga Hufflepuff here," she said nervously.
Helga served Rowena. She was a loyal and hardworking one, keep to take on any job. However, it was not a servant and mistress relationship, it was a deep friendship almost sister like, just like Godric and Salazar(though in their case it would be brother like!). The four soon became very good friends. Rowena told them all sorts of stories. She did not own the castle. She had just gone wandering one day when she came across it. It was already dark so she spent the night there, conjuring up food when she was hungry. Then, one day, out of the distance, she saw a girl, perhaps the same age as she was, wandering. Just wandering. In the misty moors and silent surroundings. It was Helga.
Helga was forever grateful to Rowena and kept her loyalty to her. Any secrets were kept between them, any worries would be sorted out but kept to themselves. It had been like this for five years. Now, they had company. They could all be really good friends! Well why not?
i know, i know! The real version is probably written somewhere in the books.
But this is my version! Enjoy!
