One common theme is forbidden love. Often, sabertooths from different groups or with different statuses fall in love, which is not allowed in their society. For example, a low - ranked sabertooth might fall for a high - ranked one.
Indeed, Wolverine and Sabertooth are considered brothers in the comics. However, their interactions are filled with rivalry and hostility, making their brotherhood a very strained one.
One possibility could be a story of an unlikely friendship. The female human, perhaps a fearless adventurer in Skyrim, stumbles upon a male sabertooth. Instead of attacking each other, they gradually form a bond. The human could use her intelligence to help the sabertooth when it's injured, and the sabertooth could use its strength to protect the human in dangerous situations in the wilds of Skyrim.
I'm not sure specifically as I haven't read it. But generally, if it's a fanfic about a sabertooth, it might be about Bella's adventures in a world related to sabertooths, perhaps she has some special relationship with them, like befriending a sabertooth or being part of a story where sabertooths play a crucial role.
Sorry, I have no information regarding the author of this particular fanfic. It could be an amateur writer who just shared it on a small fanfic community, or it could be someone more well - known within the sabertooth or relevant fandom, but without further research, there's no way to tell.
Definitely not. Harry Potter has a rich and detailed lore of its own. It follows the adventures of Harry, Hermione, and Ron in a world full of magic, mystery, and danger. Sabertooth fanfiction, on the other hand, would be related to the Sabertooth concept which has no connection to the world of Harry Potter. The magical elements in Harry Potter like the Philosopher's Stone, the Marauder's Map, and the various magical creatures are unique to its own universe and not borrowed from Sabertooth fanfiction.
