The Pied Piper was a man with a unique talent for playing the pipe. He showed up in the town that was overrun by rats. He made an offer to the townspeople to get rid of the rats in exchange for a payment. His appearance was quite distinct, with his pied clothing. His music was so enchanting that it could lead living things, first the rats and later the children, to follow him.
The Pied Piper was a strange man who came to the town of Hamelin. He was dressed in very colorful, pied (meaning having two or more different colors) clothes.

Since I don't know the specific 'quinn the new york story', Quinn could be anyone. It might be a young person starting a new life in New York, a native New Yorker with a unique story, or perhaps an immigrant who is trying to find their place in the city.
Maybe a character from their past who has a hidden grudge. Say, someone they defeated in a previous battle who has now found a way to get revenge. This person could pretend to be their ally again and then stab them in the back when they least expect it.
Roddy Piper was a prominent figure in the world of wrestling. He had a very distinct look and was known for his intense rivalries. He was one of those wrestlers who could really engage the audience with his in - ring performances and his ability to stir up drama, which often led to controversy.
In the fanfiction, it's very possible that Puck would be at Quinn's side during labor. He has a history with her and would surely care about her well - being. Her best friends from Glee club would also be around. Rachel, with her big heart, would probably be there offering words of encouragement. Finn, being a good friend, would also show up. And Santana, who has a strong bond with Quinn, would be there to give her strength and sass when needed.
I'm not sure who exactly Sebastian Quinn is in this context without more information. It could be a character in a movie, a book, or some other form of media that is based on a real - life story.
