"Hey, everyone," Tony said, once people had gathered. "We're going to talk about shielding today. Or defenses, in general, since everyone's magic is a little different. First, Karla's going to talk a bit about shields. Karla?"
Tony stepped aside and let Karla tag in
speak and answer any questions. Once she was done, Tony addressed the group again. "Who else feels comfortable enough with defensive magic to help others?
Raise your hand, please?" Wow, he felt like a teacher or something. Way weird. Assuming there were hands up, he continued. "Okay, everyone else? These are the guys you go to for help."
"One last thing for today -
let's talk strategy. Karla suggested that we find a few places on the island that are easy to defend and practice shielding those spots. Where do you guys think those places are? And what else can we do to make those spots ready for an invasion - like, maybe have food and first aid stuff staged there?"
