Yes, there are quite a few. You can find them on various fanfiction websites like FanFiction.net. Some might focus on a character from the Harry Potter world being trained in combat in a unique way, perhaps with a new mentor or in a different magical setting.
One common theme is self - discovery. As the character is trained as a warrior, they learn more about their own abilities and potential. Another is friendship, as they often rely on their friends during the training process.
No. Liches are often associated with dark and unethical magic. Harry has always been on the side of good and learning from a lich could corrupt his values.
Zelretch is likely a very powerful and perhaps mysterious character in this fanfiction. He could be an ancient wizard or a being from a different magical dimension with knowledge far beyond what is known in the normal Harry Potter universe.
Yes, there might be. The 'Star Wars' and 'Harry Potter' universes are both extremely popular, and the idea of Harry Potter training Anakin Skywalker is an interesting crossover concept. There are many fanfiction websites out there, like FanFiction.net and Archive of Our Own, where fans often create unique crossovers. You can search on these platforms using relevant keywords to find such a fanfiction.
Azura could be an original character created for this fanfiction. Maybe she's a powerful witch from a far - off land with her own unique brand of magic.
Well, without reading it specifically, it might be about Harry Potter getting trained by greybeards. Maybe these greybeards are some kind of wise old wizards who impart special knowledge or skills to Harry that he didn't get at Hogwarts. It could involve new forms of magic, different ways of dealing with dark forces, or perhaps a whole new adventure that takes Harry outside the normal realm of the wizarding world he knows.
It could be Zeus. He is a powerful god and might see Harry as a worthy candidate for training. He could teach Harry about leadership and power control.
Well, one possibility is that Harry would become an even more powerful wizard. Merlin could teach him ancient spells and magic that are long forgotten in the wizarding world of Harry's time. Harry might gain a deeper understanding of magic's origin and be able to use magic in ways that are more instinctive and powerful. He could also learn about different magical cultures from Merlin's vast experience.
