Long ago, a terrible war threatened the very existence of our entire continent. Using the Power of the Outsider, the founder of the House of Arganan built a great moving fortress, operable only by one who bears the Outsider’s mark.
The overwhelming power of the moving fortress served as a deterrent and brought an end to the war. Afterwards, to prevent anyone misusing this terrible power, it was then sealed away, and now only a legend remains:
“When crisis befalls Lazulis, one shall appear who bears the Mark of the Outsider, and he shall be the island’s savior.”
