Hazardous Waste at the AoAF

Here's yet another scene. A few minutes after the characters landed at the Academy of Armed Forces (the real Academy of Evil, because it's a military school with an ultra-rigid system. This means that if you botch or make a false move, you're basically thrown in the stockades. Is there anything that could go any worse?), they descry a neglected barrel of nuclear waste. After seeing that the barrel was on the school grounds, they get suspicious. Could someone have deliberately rigged the campus with a colossal quantity of toxic waste? Find out... and watch out!

No explicit critiques, please.
