During the good ending, players are able to seal off the repository, ensuring that no other witches or wizards would ever be able to harness its power again. Players don't get to see their choice fleshed out in-game sadly, but the implications are enough to warrant some considerable thought.

That being said, choosing an ending in Hogwarts Legacy is still a major decision, as it sets in stone the theoretical fate of the protagonist and the wizarding community around them. While there may be some different dialogue options, they don't affect the student's actions, NPC relationships, or the direction of the mission. Furthermore, no real opportunities for a diverging storyline present themselves during the game's main quests.

This unfortunate truth is made apparent from the game's lack of a morality system no matter how kind or how evil a student is in their day-to-day actions, they'll still have access to all three of Hogwarts Legacy's endings. Unsurprisingly, one the biggest choices in Hogwarts Legacy is which ending players pick - however, its impact isn't as great as some might expect.
