This device utilizes Mind and essentially causes anyone seeing the ship to regard it as Someone Else's Problem. The main bug with this device is that the ship must be painted pink in order for it to function properly. Still, the idea intruiges many in the tradition. As mentioned before, the airship is a research platform. It's crew has discovered that the upper atmosphere has it's own version of ley lines, analogous to the jet stream and other meteorological phenomena.
Nodes are far less permanent, and much more violent.
They take the form of large cyclonic storms like hurricanes and tornadoes. Thunderstorms are a bit calmer and the ship usually recharges it's batteries in these. However, it can be occasionally be found floating serenely in the eye of a hurricane, studying the weather's effects on the umbra and earth. The airship is normally found offshore, or over mountain ranges. Even with the capabilities of this ship, it's not wise to attract undue technocratic attention.
