Snape's help could have a huge impact on Harry's Hogwarts journey. For example, he might give Harry tips on dealing with certain dark magic threats secretly.

One interesting plot point could be how Snape first decides to help Harry. Maybe it's because he sees a glimmer of Lily in Harry, or perhaps there's a new threat that forces him to put aside his grudges. Another could be the way Harry reacts to Snape's help. At first, he might be very suspicious since they have a rocky history in the original story.

There might be some out there in the vast world of fanfiction, but it's not a common or well - known type.

If Harry Potter gets help from the Queen in fanfiction, the Queen could offer her strategic wisdom.
