The Jade Rabbit

What kind of harebrained scheme have you got in mind this time?
Like many weapons of the Dark Age, the Jade Rabbit was created from hastily reassembled—and often poorly understood—Golden Age technology: in this case, kinetic low-atmosphere propulsion systems in use on Luna settlements. Even the weapon's casing is cut from the plasteel bulwarks of the First Light installation.

The significance of the markings: 玉兔, or “Jade Rabbit,” are unfortunately lost to history.
