Occasionally, Ze Arch sends us the embodiment of its spirit in the form of large, blue, glowy, jelly-like ships. We've discovered that The Order tends to like to help said spirits back on their way to the ephemeral beyond so that it may rejoin the cosmos and watch over us always.
We don't sit in Gallia, we frequent Sirius to shoot hostile rocks and steal their shiny ore for Ze Arch.
