I don't have enough information to say for sure. It could be a new character created by the fanfic author or it might feature characters from the original source material if it's based on something.
Another possible main character could be a young witch from the northern wizarding community who has a special connection to the local magic.

I'm not sure specifically as it depends on the particular 'oc in the north fanfiction'.

Perhaps there is a young hero in 'the dragon in the north fanfiction' who is on a quest and stumbles upon the dragon in the north. And of course, the dragon is likely to be a major character.

Most likely the Starks would be main characters. Jon Snow, as he has strong ties to the North and is a natural leader. Sansa Stark too, with her new - found political acumen. Arya could also be important as she has her own brand of justice she might bring to the North's cause.
In addition to the regular Harry Potter crew, there could be a character who is a native of the 'Lord of the North' and acts as a guide for Harry and the others.
