It depends on who 'crank gane' is. In general, reading fanfiction is quite common among fans of various franchises. However, if 'crank gane' is an individual, it may or may not be common for them specifically. If they are part of a niche fandom, it could be a regular activity for them.
I'm not sure who 'crank gane' is. Maybe it's a specific person within a certain community. If they play and read fanfiction, it could mean they are exploring fictional worlds created by fans, perhaps for entertainment or to engage with a particular fandom.
Given the title 'Harry Robs New Mexico Story', Harry is likely the central figure. He could be a fictional character created to tell a story about the darker side of New Mexico, like crime and its consequences. Or perhaps he is based on a real - life person, and the story is a dramatized version of his actions in New Mexico. Without more context, it's hard to determine his exact identity.
It could be Hermione. She might notice that Harry's clothes are looking a bit shabby and use her cleverness to either buy or create new clothes for him. Maybe she uses a spell to transform some old fabric into a brand - new set of clothes.
Maybe a house - elf who has broken free from the traditional servitude mindset. This house - elf has developed their own magic in a different way and befriends Harry. They teach Harry about the hidden magic that house - elves possess, which is not taught in regular Hogwarts classes.
Maybe it's an old wandmaker from a far - off land. This wandmaker has been crafting wands for centuries and has a unique intuition about which wands are meant for which wizards. He sees something special in Harry and presents him with a new wand.
There might be new stories about the relationships between the characters in 'Harry Potter 6'. For example, the budding romance between Harry and Ginny could have some new side - stories, like how they dealt with the challenges of being in a relationship while fighting Voldemort.
