In the fanfiction, when Harry Potter teleports in water, there could be consequences for his own magic. It might drain his magical energy more quickly compared to teleporting on land. Since water has its own magical properties, it could be more resistant to his magic, and he would have to exert more effort. This could leave him vulnerable in case he faces an enemy shortly after teleporting in water. Also, his teleportation could cause changes in the water's temperature or flow, which could have unforeseen effects on the surrounding environment.
One potential consequence could be disrupting the natural balance of water - based magic. If he teleports too often or without proper control, it might cause ripples in the magical ecosystem of water bodies. Another consequence could be attracting unwanted attention from water - dwelling magical creatures. They might see his teleportation as an intrusion or a threat.
There could be various consequences. Firstly, a cease - and - desist order might be issued, forcing the seller to stop selling the fanfiction immediately. Secondly, the seller may have to pay damages. Since 'Harry Potter' is a very valuable brand, the damages could be substantial. And thirdly, in some cases, there could be criminal charges if the infringement is severe enough, although this is less common in cases of fanfiction sales.
The wizarding economy would be in chaos. Gringotts is the central bank of the wizarding world. Its destruction would mean that people's savings, vaults, and all the financial transactions would be disrupted. Wizards and witches would lose their trust in the financial system.
One potential consequence could be a negative impact on the original 'Harry Potter' brand image. If the fanfic contains disturbing or inappropriate content, it might turn some fans away from the overall franchise. Another consequence could be the spread of harmful ideas within the fan community. For example, if it promotes toxic relationships or unethical behavior, it could influence younger or more impressionable fans in a bad way.
One potential consequence could be a change in his relationships. His friends might be worried or even turn against him. For example, Hermione, who is always concerned about following the rules and doing what's right, would likely be very troubled. Another consequence could be a shift in his own moral compass. The dark arts are often associated with negative and unethical actions, so he could start to make more morally ambiguous decisions.
If Harry summons demons in fanfiction, he could face immediate danger. Demons are often depicted as malevolent entities. They might attack Harry instead of doing his bidding. He could also lose control of the situation, leading to chaos around him. His friends might turn against him when they discover what he's done, seeing it as a step into the dark side of magic.
Harry could put himself in great physical danger. Voldemort might not be willing to help without exacting a high price, like Harry's own life or his magic. And even if Voldemort does seem to offer help, it could be a trap to harm Harry.
One consequence could be that he loses the trust of his friends. They might be afraid that he could control them at any time.
He would likely feel a great sense of confusion and loss. His sense of self would be severely shaken without the knowledge of his name, which is such an important part of one's identity.
There could be a power struggle within the wizarding world. Some pure - blood families who have long held influence in the Wizengamot might oppose Harry's control. This could lead to internal conflicts, maybe even a split in the wizarding community between those who support Harry and those who don't.
If Harry uses his space - time control abilities in the fanfiction, he might accidentally create alternate timelines. For example, if he saves a character who was supposed to die, that character could then go on to make different choices that change the entire course of events. This could lead to a situation where the world he knew is no longer the same, and he has to deal with the chaos of these new timelines.
