Sael watched as what he called his "raid boss" armor prototype landed with a thunderous boom. Towering twenty feet tall it was a mass of enchanted steel and countless magical components combined into a hulking armor that was his take on a magically powered exosuit.

Beneath her feet, the castle's stone gave way, absorbing as much as it could before collapsing into a small crater.
