A Fluttering Weapon

Exploration Stage: Historical Museum
From: Janko
Description: There are so many interesting things found in the latest expedition! It’s not clear what could be creating the anomaly, but I think it’s something mechanical. Let’s look for an item with gears.
Completed: A toy butterfly? Wait, my father told me about the Puppeteer’s Butterflies of Retribution, a weapon against flying monsters used by the Defenders. What an exhibit!
