I'm not sure specifically as I haven't come across a fanfic with this exact title. It could potentially be about a character named Harry from Ravenclaw house in a fictional world where 'gallons' might be a form of currency or some sort of measurement, and 'foreseen' could imply something predicted. Maybe it's about his departure in a situation related to those elements.
There are several places you could look for this fanfic. First, as mentioned before, Archive of Our Own and FanFiction.net are great resources. Another option is to check any Harry Potter - themed fanfic communities or forums. Sometimes, fans will share links to unique or hard - to - find fanfics in those places. However, keep in mind that not all fanfics are easy to track down, especially if they are relatively new or by an unknown author.
One possible plot could be that Harry has a major disagreement with Ravenclaw values. Maybe he feels that Ravenclaw's focus on knowledge and intellect has been misused in some way within the wizarding world. For example, he discovers that some Ravenclaw descendants are using their intelligence to create dark spells under the guise of academic research. This could lead him to publicly disown Ravenclaw as a house, causing a huge uproar in the Hogwarts community.
Yes, there could be. Maybe in a Ravenclaw fanfic, Gallons could be a magical item or a unit of measurement in a very unique magical system created by the author. For Harry fanfics related to this, it could be part of a side - plot where a Ravenclaw character is involved with something related to Gallons. It's all about the wild and creative interpretations that fanfic writers can come up with.
In a Ravenclaw fanfic, Gallons might be part of a complex magical formula or a key to unlocking a Ravenclaw's hidden chamber. In the context of a Harry fanfic, perhaps it's a new discovery that ties into the overall plot of the wizarding world. It could be a currency in a magical economy that only Ravenclaws understand fully, and Harry has to learn about it to solve a problem. This would add an interesting dimension to both types of fanfics.
I'm not entirely sure as it's a very specific fanfic. It might be about Harry having some sort of conflict regarding Ravenclaw money, perhaps he disowns it for reasons that were foreseen in the fan - created plot. Maybe there are issues like inheritance, or some magical connection to Ravenclaw's wealth that he doesn't want to be part of.
It could be a Ravenclaw student who has been misusing their intelligence. They might be creating chaos in the wizarding world, and Harry's disowning of Ravenclaw could be his way of standing up against this misuse. This student could be jealous of Harry's fame and try to undermine him by causing problems that would make Harry take such a drastic step.
Obviously Harry is one of the main characters since his name is in the title. It's also possible that there could be characters related to Ravenclaw, like Luna Lovegood who could be involved in the story about Ravenclaw money. Maybe there are also some original characters created by the fanfic author to help drive the plot forward regarding this money issue.
It could be the amount of a rare magical substance needed to power a magical device. For example, a time - turning device might require exactly three gallons of a special elixir to work properly.
It could be used to flood an area for a magical prank. Some mischievous characters in the Harry Potter fanfic might use the three gallons of a magically - created liquid to flood a corridor in Hogwarts, causing chaos and laughter among the students.
