My potter fanfic makes Harry’s time in canon… a cakewalk. I do stray a bit OOC because I do have the death eaters effective in their designs and plans. I also let myself get bogged down in the details, but that captures the grind that Harry would experience in this, as he steadily becomes persona-non-grata throughout the wizarding world, unable to stop the slog of negative press slandering him. It’s enjoyable to keep writing here, because the narrative is so addictive for what comes next; even on the rewrite, despite knowing, it’s still enjoyable.
For other fandoms, I occasionally do get thoughts, mostly of the mary/gary sue variety, nothing worth writing about TBH, because original works is where the rest of my fun writing is at.
