The region of Caledon Perenelle has recently been discovered on the Caledon Archipelago, and I am dedicatedly perusing the assorted journals, maps, sketches, papers and various pieces of what is quite frankly Junk and Flotsam, left to me by my Great-Uncle regarding this Peculiar Area. Doubtless things will be revealed soon enough; if only he had not used such an Annoyingly Semi-Penetrable Cypher.
One piece of the Puzzle which I have Solved, though, is Great-Uncle's use of specialised Umbrellas. Whilst, being a Malaprop of the Hertfordshire Malaprops, he obviously preferred Dirigibles in practice, it seems that during his Expedition he and his compatriots frequently used a particular brand of Umbrella for short journeys.
This somewhat heavy parapluie, constructed from the hide of a beast frankly unknown to me, is impregnated with some form of propulsive on the inner surface, and with careful manipulation a Holder may propel themselves aerially. Other Umbrellas are more wilful, and do not care a jot what their Holders wish, but I would not put those out for Money, really, for fear of Complaints.
The upshot of all of this is that the Ordinal Transitory Umbrella is now currently On Sale for a mere Fifty Linden Dollars. Should you be interested, please do see my Caledon shop, or in fact Caledon Perenelle, or if you insist, its listing on that dratted Xstreet thing.
