Harry Potter - On the topic of Goblins
We've all read docs where Harry ends up in Gringots getting his horcrux removed by Goblin healers, and finds out that they hate horcrux's because it's "the darkest of magics". I cannot remember a single fic which does this trope right. And so I offer a few tips to anyone who hopes to include this plot point in their stories.
1. Give a believable reason for the hate. Goblins should not give a damn about "dark magic". They are concerned with money, their property, and in some cases honour. But they are warriors, "dark magic" shouldn't garner such unwarranted hatred. Instead, give them a personal grievance with horcruxes. There were a lot of Goblin/Wizard wars, so maybe Wizards using Horcuxes were a major problem for Goblins during the time, what with the coming back from the dead thing. It's more believable than hatred of "dark magic"
2. Goblin healers should not be the kind matrons they are portrayed as. They should be just as ruthless as the rest of them. For a warrior race like Goblins, a healer would be seen as a position that most hate. A punishment, like the Sontarons from doctor who. Not some overly fussy momma Goblin.
3. If you must give the Goblins, a 'super special secret soul remover' spell, explain it with more of a description than that. Goblins should not be wildly knowledgeable of soul magic, or most magic at all. Maybe they forced a wizard to make it and stole it. It would fit in with their ruthlessness and gives a semi reasonable explanation for how they got it. Maybe they also wiped out knowledge of horcruxes as well to try and prevent more from being made in the future. I don't know, these have been a few tips.
