It's not really an error, just letting you know how things will run, since you're the first to touch upon the uniforms in your CS. :P Yep, everyone's on the airship. People can possibly be on different airships as they converge to Beacon, if they're from different parts of Vale and Remnant, but you can post when you want. You can also start the post before you get on, if you wanna give some exposition, just say, like, "10 minutes prior."
