Are there any good storys in which Grindelwald plays a major role? I think Grindelwald is one of the most interesting characters and it´s dissapointing that there aren't any good storys with him.

Do any of you have a suggestion of a good one, maybe with Harry travelling in time to WW2 which is actually good the only story which I could find where he is really cool is Santi's fic and even than his role is minor.

 

In this story Harry travels back in time to Grindelwalds time and fight him and his forces. https://m.fanfiction.net/s/3155057/1/Altered-Destinies
This thread probably belongs in the story search forum btw.

 

Escape to Darkness by kmfrank.

One of my absolute favourites, and utterly awesome - beginning with Harry and Grindelwald escaping from Nurmengard.
