I'll take a shot.
There is a curiously circular lake now known as Lake Fate occupying the former first site of the Undead Thread, AKA "Flying Castle."
Using the mineral wealth we found in the shattered substrata of what we suspected at the time was a meteoric impact crater, long eroded to invisibility, we built the castle and excavated a large amount of the crater material, lifting it with huge balloons and enormous jet engines.
That sufficed to get us to Loch Ness, from which base we made a beer run for some Guinness.
It having been discussed to take the now aptly named Flying Castle into outer space, some modifications were necessary.
In the Norwegian Sea we picked up a special "girdle" we call the Thrust Ring, and then we continued over the North Pole to the island of Kauai in Hawaii.
We stayed there for some time while refitting for our space launch. We needed nuclear fuel for the new engines, so we filtered Uranium from ocean water, (We were floating in the Pacific near the island.)
After additional refitting, we used the balloons and jet engines for the last time, to take us to Eniwetok Atoll, for our final fuel acquisition and for mounting the two additional Habitats we needed for rotational stability and producing sufficient food and oxygen for our passengers and crew.
We took off from the surface of the Pacific just east of Eniwetok, using our nuclear rocket engines mounted in "Shuttle Thrusters." These are stub-winged rocket vessels similar in appearance to the Space Shuttles, though considerably more powerful, being nuclear powered and carrying fuel tanks.
These shuttles also double as our emergency life-boats, should the need to abandon the Flying Castle ever come about. They can also be used to make excursions to other interesting locations in the solar system.
