Deadly Cargo

OK, let's finish our exciting journey into the past and get back to our problems in the real world. The cultists we'd driven away from the tower ruins complained to their master, and he sent a strike force against us. Luckily, the punishers have to overcome piles of garbage to get here, so we have some time to prepare a surprise for them.
One of the Imperial ships had explosives in its hold. Miraculously, they survived the shipwreck, and now they will come in handy. Inspect the ship's frame carefully, collect some five mines and call me to find out the details of our sophisticated plan.

If you crack a joke about a warm welcome, you'll disappoint me greatly.

Take a look: good as new! Glory to Imperial science: whilst the mechanism is not loaded, you can play goblinball with them.
