Welcome to the game! This is where you can ask the DM (me) out-of-character questions about stuff like actions you want to take, rules to work over, etc.

For my first player, we were discussing the details of the school before we can recruit others.

So I looked over the options in W&W, and found myself gravitating toward Ilvermorny as a possible school to use for this campaign; it's the American wizarding school, the "youngest" and least elitist of the schools, and the Irish and Native American roots are interesting. We could do that, or if you like I/we can just come up with a totally new school.

Either way, I'm definitely putting in NPCs of my own design when it comes to staff, the headmaster, and stuff like that.
