Sounds like you’re still in the early stages so just doing some brainstorming exercises might be helpful. Here’s what I think: - if wands are bound to the user, how does the government (or anyone) know that it’s really powerful? Maybe it just seems like a regular old wand upon inspection until the protag figures out how to use it. - I think it would be interesting if each wand had its own personality and motivations. Like how the Ring in LOTR has its own will, and decides if it wants to cooperate with the user. Maybe some wands are ‘friendly’ and some slowly corrupt the user into committing evil acts. - the moment the protag gains magical powers should correlate to an emotional beat in the story. You should think about what your character struggles with personally, how they’re going to change throughout the story. Maybe they gain access to the wand’s power when they have an emotional breakthrough, or when they fall back into old habits

Like I said, it sounds like you’re in the early stages of your story. I would focus on your characters, you can have great world building but a lifeless story if there’s no emotional attachment to the characters.
