Hail my good tween fellows! Wish you to learn more about the great engines that rent the walls of castles asunder? Verily, come to the terrace room to learn about how these great machines worked and how to build your own to cause destruction on a scale smaller than in times of yore, but no less fun!

Each month will focus on a different machine:

9/28 - Ballista

10/26 - Catapult

11/23 - Trebuchet

Supplies will be limited. First come, first served.
